5f2323658e drm/amdgpu: add irq domain support
Hardware blocks on the GPU like ACP generate interrupts in
the GPU interrupt controller, but are driven by a separate
driver.  Add an irq domain to the GPU driver so that
blocks like ACP can register a Linux interrupt.

ba228ac8f5 drm/amdgpu/cgs: add an interface to access PCI resources
This provides an interface to get access to the base address
of PCI resources (MMIO, DOORBELL, etc.).  Only MMIO and
DOORBELL are implemented right now.  This is necessary to
properly utilize shared drivers on platform devices.  IP
modules can use this interface to get the base address
of the resource and add any additional offset and set the
size when setting up the platform driver(s).

6a53b31349 drm: powerplay: use div64_s64 instead of do_div
The newly added code for Fiji creates a correct compiler warning
about invalid use of the do_div macro:

In file included from powerplay/hwmgr/ppatomctrl.c:31:0:
drivers/gpu/drm/amd/amdgpu/../powerplay/hwmgr/ppevvmath.h: In function 'fDivide':
drivers/gpu/drm/amd/amdgpu/../powerplay/hwmgr/ppevvmath.h:382:89: warning: comparison of distinct pointer types lacks a cast
     do_div(longlongX, longlongY); /*Q(32,32) divided by Q(16,16) = Q(16,16) Back to original format */

do_div() divides an unsigned 64-bit number by an unsigned 32-bit number.
The code instead wants to divide two signed 64-bit numbers, which is done
using the div64_s64 function.
