[PATCH] ARM: imx: ddr: Fill in missing DDRC ZQCTLx on i.MX7

[sbabic at denx.de]

> The iMX7 defines further DDRC ZQCTLx registers, however those were
> thus far missing from the list of registers and not programmed. On
> systems with LPDDR2 or DDR3, those registers must be programmed with
> correct values, otherwise the DRAM may not work. However, existing
> systems which worked without programming these registers before are
> now setting those registers to 0, which is the default value, so no
> functional change there.
