Marek Vasut 0e06d63d19 ARM: imx: ddr: Add missing PHY reset 
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 .
