[U-Boot] [PATCH] ARM: OMAP4: Correct the lpddr2 io settings register value.

[U-Boot] [PATCH] ARM: OMAP4: Correct the lpddr2 io settings register value.

[R Sricharan]

To meet certain timing requirements on the lpddr2 cmd and data phy
interfaces ,lpddr iopads have to be configured as differential buffers
and a Vref has to be internally generated and provided to these buffers.

Correcting the above settings here.
