drivers/genesyslogic/gl9763e: Fix boot on eMMC failed issue on Volteer
Booting on Kingston (EMMC64G-TA29/TX29-HP) and Hynix (H26M74002HMR) eMMC
currently fails due to R/W error. This is a workaround to finetune the
data latch timing by verdor-specific setting of GL9763E. For improving
the compatibility of GL9763E with these two eMMC.
