Add a debugfs entry showing the use-count for all power domains of each
power well.
v3: address comments from Paulo:
- simplify power_domain_str() by using a switch table
- move power_well::domain_count to power_domains
- WARN_ON decrementing a 0 refcount

So far we distinguished platforms without a dynamic power well with
the HAS_POWER_WELL macro and for such platforms we didn't call any power
domain functions. Instead of doing this check we can add an always-on
power well for these platforms and call the power domain functions
unconditionally. For always-on power wells we only increase/decrease
their refcounts, otherwise they are nop.
This makes high level driver code more readable and as a bonus provides
some idea of the current power domains state for all platforms (once
the relevant debugfs entry is added).

In intel_display_capture_error_state we use HAS_POWER_WELL to check if
we are running on Haswell/Broadwell when accessing HSW_PWR_WELL_DRIVER
which is specific to these platforms. Future platforms with power wells
don't have this register, so HAS_POWER_WELL won't work there any more.
Use IS_HASWELL/IS_BROADWELL instead.

Instead of using a separate function to check whether a power domain is
is always on, add an always-on power well covering all these power
domains and do the usual get/put on these unconditionally. Since we
don't assign a .set handler for these the get/put won't have any effect
besides the adjusted refcount.
This makes the code more readable and provides debug info also on the
use of always-on power wells (once the relevant debugfs entry is added.)

HW generations so far had only one always-on power well and optionally
one dynamic power well. Upcoming HW gens may have multiple dynamic power
wells, so add some infrastructure to support them.
The idea is to keep the existing power domain API used by the rest of
the driver and create a mapping between these power domains and the
underlying power wells. This mapping can differ from one HW to another
but high level driver code doesn't need to know about this. Through the
existing get/put API it would just ask for a given power domain and the
power domain framework would make sure the relevant power wells get
enabled in the right order.

I believe, and an evening of i-g-t, that our original workaround for the
missed interrupts on Sandybridge, that of holding forcewake whilst we
wait for an interrupts, is no longer required. This leaves us dependent
on the second workaround of forcing an UC read of the ACTHD before
reading back the seqno from the snooped HWS. Dropping the forcewake
should allow us to conserve a little power, not much as the GPU is meant
to be busy whilst we wait for it!

Addresses
"[BUG] completely bonkers use of set_need_resched + VM_FAULT_NOPAGE".
In the first occurence it was used to try to be nice while releasing the
mmap_sem and retrying the fault to work around a locking inversion.
The second occurence was never used.
There has been some discussion whether we should change the locking order to
mmap_sem -> bo_reserve. This patch doesn't address that issue, and leaves
that locking order undefined. The solution that we release the mmap_sem if
tryreserve fails and wait for the buffer to become unreserved is something
we want in any case, and follows how the core vm system waits for pages
to be come unlocked while releasing the mmap_sem.
The code also outlines what needs to be changed if we want to establish the
locking order as mmap_sem -> bo::reserve.
One slight issue that remains with this code is that the fault handler might
be prone to starvation if another thread countinously reserves the buffer.
IMO that usage pattern is highly unlikely.

If ttm_bo_move_memcpy was instructed to move a non-populated ttm to
io memory, it would first populate the ttm, then move the data and then
destroy the ttm. That's stupid. However, some drivers might have relied on
this to clear io memory from old stuff. So instead of a NOP, which would
be the most efficient, just clear the destination.

Pull i2c changes from Wolfram Sang:
- new drivers for exynos5, bcm kona, and st micro
- bigger overhauls for drivers mxs and rcar
- typical driver bugfixes, cleanups, improvements
- got rid of the superfluous 'driver' member in i2c_client struct This
touches a few drivers in other subsystems. All acked.

We must have one to fill out the adjusted_mode.crtc_clock. And with
the tv encoder fixed up every encoder we have has a ->get_config
callback. So we can drop the checks.

We need this to properly fill in adjusted_mode.crtc_clock, otherwise
the state checker gets unhappy. This seems to have been forgotten in
the big clock rework in

It seems we do have machines with 3 HDMI/DVI outputs, so sharing
WRPLLs is the only way to get 3 pipes working.
