[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 invalid test GRANULARITY access counter parameter.

It should return invalid parameter beyond SZ_64M.
In KMD there is no conditional check beyond SZ_64M,
KMD need to be updated with the conditional check.
Until then the test will be passed.
Below is the KMD code.
granularity_in_byte(int val)
case 0:
return SZ_128K;
case 1:
return SZ_2M;
case 2:
return SZ_16M;
case 3:
return SZ_64M;
default:
return 0;

v2: Added subtest description.
