mmc: sdhci-of-esdhc: fix the mmc error after sleep on ls1046ardb

commit f2bc600008bd6f7f5d0b6b56238d14f95cd454d2 upstream.

When system wakes up from sleep on ls1046ardb, the SD operation fails
with mmc error messages since ESDHC_TB_EN bit couldn't be cleaned by
eSDHC_SYSCTL[RSTA]. It's proper to clean this bit in esdhc_reset()
rather than in probe.
