This reverts commit eb0e5fa310.
Reason for revert: fix ARCVM test regressions while investigating root cause (b/371862010).
Original change's description:
> gralloc: Error when locking buffer alloc'd without CPU_ usage
>
> ... except when running with software rendering as apps do not
> know that they would need to request additional CPU_* usage
> for GPU_* usage.
>
> Bug: b/356845188
> Test: cts -m CtsNativeHardwareTestCases
