In the AMD powerplay driver, a pointer is checked for validity by
comparing against an integer '0', which causes a harmless warning
when building with "make W=1":
drivers/gpu/drm/amd/amdgpu/../powerplay/hwmgr/processpptables.c:1502:16: error: ordered comparison of pointer with integer zero [-Werror=extra]
This changes the code to the more conventional "if (pointer)" check.

The cast to uint8_t happens before the right shift so this always sets
.m3arb to zero. The cast is actually a no-op so we can remove it.

The hwmgr handles all hardware related calls, including clock/power
gating control, DPM, read and parse PPTable, etc.
v5: squash in fixes
v4: implement acpi's atcs function use cgs interface
v3: fix code style error and add big-endian mode support.
v2: use cgs interface directly in hwmgr sub-module
