[igt-dev] [PATCH i-g-t] tests/xe/xe_access_counter: Negative access counter test

[priyanka.dandamudi at intel.com]

From: Priyanka Dandamudi <priyanka.dandamudi at intel.com>

Added a negative test related to access counter.
It tries to test GRANULARITY access counter parameter.
It should return -EINVAL parameter beyond SZ_64M.

v2: Added subtest description.
