target: msm8996: Do not switch to legacy mmc mode during lk exit

Switching to legacy mmc mode was required for hlos driver to function
properly, this was needed since the vendor specific register was not
reset during controller reset. The right solution to this is to reset
the vendor specific register during the init of the hlos driver.
