[PATCH] ARM: imx: ddr: Add missing PHY reset

[sbabic at denx.de]

> The iMX7D RM 9.2.4.9.3 Power removal flow Table 9-11. Re-enabling power
> explicitly says both the DDR controller and the PHY must be reset in the
> correct sequence. Currently the code only resets the controller. This
> leads to a misbehavior where the system brings the DRAM up after reboot,
> but the DRAM is unstable. Add the missing reset.
> The easiest way to trigger this is by triggering WDT without having the
> WDT assert WDOG_B signal, i.e. mw.w 0x30280000 0x25 .
