Alex Deucher f3b37ebf2c drm/amdgpu: fix SPDX headers on amdgpu_cper.c/h
These should be MIT.  The driver in general is MIT and
the license text at the top of the files is MIT so fix
it.

Liao Yuanhong 7670daf65a drm/amdgpu/amdgpu_cper: Remove redundant ternary operators
For ternary operators in the form of "a ? false : true", if 'a' itself
returns a boolean result, the ternary operator can be omitted. Remove
redundant ternary operators to clean up the code.

Victor Skvortsov 3394069e7d drm/amdgpu: Disable ACA on VFs
VFs query RAS error counts directly from host with
AMDGPU_RAS_VIRT_ERROR_COUNT_QUERY. When ACA is enabled,
an unusable aca_sysfs is created rather than amdgpu_ras_sysfs_create()

Likewise, VFs depend on host support to query CPERs, rather than ACA component.
