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.
