If max_discard_to was not designed, for mmc card preferred erase

limit for data transfer, Use max_discard_to as max data timeout value

eSDHC host don't have a standand power control register.
Also eSDHC host which support spec 1.0 and spec 2.0 don't
support voltage switch. So add this change avoid writing other

A-003980: SDHC: Glitch is generated on the card clock with software reset or
clock divider change
Description: A glitch may occur on the SDHC card clock when the software sets
the RSTA bit (software reset) in the system control register. It can also be
generated by setting the clock divider value.
