anv/icl: Disable prefetching of sampler state entries

Browse Source 
WA_1606682166:
Incorrect TDL's SSP address shift in SARB for 16:6 & 18:8 modes.
Disable the Sampler state prefetch functionality in the SARB by
programming 0xB000[30] to '1'. This is to be done at boot time and
the feature must remain disabled permanently.
