soc/intel/bdw,nb/intel/hsw: convert panel delays to ms representation
For easier review of the switch to a new register struct in the follow-up change, the panel delay times get converted from destination register raw format to milliseconds representation in this change. Formula for conversion of power cycle delay: gpu_panel_power_cycle_delay_ms = (gpu_panel_power_cycle_delay - 1) * 100 Formula for all others: gpu_panel_power_X_delay_ms = gpu_panel_power_X_delay / 10 The register names gain a suffix `_ms` and calculation of the destination register raw values gets done in gma code now.
