These should be MIT. The driver in general is MIT and
the license text at the top of the files is MIT so fix

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.

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.
