Update xe_hwmon_pcode_read_power_limit() and xe_hwmon_pcode_rmw_power_limit() to read the accepted power limit for discrete platforms post CRI. For platforms before CRI only the last written pcode value was available. From CRI onwards, pcode exposes a new param2 value 2 that allows reading the accepted power limit by the hardware. v2: - Read resolved power limit in xe_hwmon_pcode_rmw_power_limit() as well. (Badal) - Rephrase commit message. (Badal) - Add prepare_power_limit_param2() to prepare param2 for mailbox power limit read.
