sparc64: Fix PCI error interrupt registry on PSYCHO.
[ Upstream commit 80a56ab626c70468be92e74cf3d288ffaed23fdb ]
We need to pass IRQF_SHARED, otherwise we get things like:
IRQ handler type mismatch for IRQ 33
current handler: PSYCHO_UE
Call Trace:
[000000000048394c] request_irq+0xac/0x120
[00000000007c5f6c] psycho_scan_bus+0x98/0x158

[00000000006ae1d0] rest_init+0x10/0x60
on e3500 and similar systems.
On a single board, the UE interrupts of two Psycho nodes
are funneled through the same interrupt, from of_debug=3
dump:
/pci@b,4000: direct translate 2ee --> 21
...
/pci@b,2000: direct translate 2ee --> 21
Decimal "33" mentioned above is the hex "21" mentioned here.
Thanks to Meelis Roos for dumps and testing.
