Actual Behavior

Issue moved from oneapi-src/level-zero#441

Sysman power reporting on iGPUs (Alder Lake, Meteor Lake, Lunar Lake) works on Windows but is broken on Linux:

counter on Intel iGPUs	Windows	Linux
zesDeviceGetCardPowerDomain()	❌ returns ZE_RESULT_ERROR_UNSUPPORTED_FEATURE	❌ returns ZE_RESULT_ERROR_UNSUPPORTED_FEATURE
zesDeviceEnumPowerDomains()	✅ returns ZE_RESULT_SUCCESS and returns one valid zes_pwr_handle_t	❌ returns ZE_RESULT_SUCCESS but no zes_pwr_handle_t

Expected Behavior

iGPU power counters should also be available on Linux.
