[U-Boot] [PATCH 02/13] arm: emif-common: Add ecc specific emif registers

[Lokesh Vutla]

This is a slight difference in emif_ddr_phy_status register offsets for
DRA7xx/keystone EMIF and older versions. And ecc registers are available only
in DRA7xx EMIF. Add support for this difference and ecc registers.
