Extend the mlx4_cq_resize() API with a way to set the "collapsed" flag
for the CQ being created.

The call to mlx4_MODIFY_CQ() had a typo so that mlx4_cq_resize() was
actually asking the FW to modify a CQ's interrupt moderation rather than
asking it to resize a CQ.

Commit ee49bd93 ("mlx4_core: Reset device when internal error is
detected") introduced some section mismatch problems when
CONFIG_HOTPLUG=n, because the error recovery code tears down and
reinitializes the device after everything is loaded, which ends up
calling into lots of code marked __devinit and __devexit from regular
.text. Fix this by getting rid of these now-incorrect section
markers.

The reserved6 field should be 64 bits, not just 16 bits. Without
this, the structure does not match the hardware layout on 32-bit
architectures: the db_rec_addr field ends up at offset 52 instead of
offset 56. The bug slipped by because the alignment of __be64 members
ends up putting it in the right place on x86-64.

Add an InfiniBand driver for Mellanox ConnectX adapters. Because
these adapters can also be used as ethernet NICs and Fibre Channel
HBAs, the driver is split into two modules:
mlx4_core: Handles low-level things like device initialization and
processing firmware commands. Also controls resource allocation
so that the InfiniBand, ethernet and FC functions can share a
device without stepping on each other.
mlx4_ib: Handles InfiniBand-specific things; plugs into the
InfiniBand midlayer.
