mmc: mtk-sd: Add stop_dly_sel and pop_en_cnt to platform data

There are modified register settings for STOP_DLY_SEL and POP_EN_CNT
from our next generation SoCs, due to the advanced chip manufacturing
process and the resulting changes in the internal signal timing.

Add two new fields to the compatibility structure to reflect the
modifications. For legacy SoCs, also add the original value of
'stop_dly_sel' to the platform data, for unified code setting.
