mb/google/brya/var/kinox: Add delay time for BH799BB rtd3
This CL adds the delay time into the RTD3 sequence, which will turn
off the eMMC controller (a true D3cold state) during the RTD3 sequence.
We checked power on sequence requires enable pin prior to reset pin
delay of 50ms and add delay of 20ms to meet the sequence on various
eMMC SKUs. Based on BH799BB_Preliminary_DS_R079_20201124.pdf in
chapter 7.2.
