[U-Boot] [PATCH v2 18/30] ARM: k2g: Program DDRPHY_DATX8 registers via mask and value variables

Different K2G evms may need to program the various
KS2_DDRPHY_DATX8_X_OFFSET registers in different ways. Therefore, use
the mask and val registers for each KS2_DDRPHY_DATAX_X_OFFSET to
properly program the register.
