Revert "rtw88: no need to set registers for SDIO"

This reverts commit 07d0f553.

For rtw88 driver, the SDIO is going to be supported, so there is
no need to remove the SDIO related power sequence settings. And
while the power sequence parser will pass in the mask of the HCI,
the SDIO part will not be used to set registers accordingly.

Moreover, the power sequence table is released as a whole package,
so the next time if we are going to update, the SDIO settings will
be overwritten. So, revert this now.
