ARM: i.MX6 Wandboard Quad: fix PBL UART MUX ...

Three variants of the Wandboard exist: WBSOLO, WBDUAL and WBQUAD.
For all variants, the external serial port is connected to UART1 via
PAD_CSI0_DATA10 (TX) and PAD_CSI0_DATA11 (RX). Unfortunately, the IOMUX
register adresses for this mux differ between i.MX6Q (WBQUAD) and others.
Make the UART IOMUX for PBL compatible for WBQUAD.

ARM: i.MX6 Wandboard: dont do MMDC Write Leveling Calibration ...

The hardware requirements to perform a write leveling calibration are
not fulfilled by the Wandboard modules.
IMX6DQRM §44.11.6 "Write leveling Calibration" Note2 states that the first
bit of each data byte group (D0, D8, ..., D56) from memory must be connected
to the same data bus bit on the controller, which is not given on the
Wandboard modules, resulting in unpredictable calib results and breaking the
WBQUAD 2GiB SDRAM setup. Similar restrictions exist for the i.MX6SD.

Remove this calibration and use the MPWLDECTRL defaults.

watchdog: i.MX: fix i.MX6 reset ...

According to the Errata ERR004346 (WDOG: WDOG SRS bit requires to be written
twice), add another two writes to ensure there must be at least two
writes happen in the same one 32kHz clock period.
Without this two additional writes, the system will not reset always.

Tested with i.MX6Quad and i.MX6 UltraLite

ARM: mvebu: fix size mask for RAM window ...

The size field in the window control register occupies bits 31:16. So
adapt ARMADA_370_XP_DDR_SIZE_MASK accordingly. This fixes detection of
RAM chips smaller than 32 MiB and so probably doesn't affect any
supported machine.

i.MX: fec: add post PHY reset delay DT property ...

Some PHY require to wait for a bit after the reset GPIO has been
toggled. This adds support for the DT property `phy-reset-post-delay`
which gives the delay in milliseconds to wait after reset.

If the DT property is not given, no delay is observed. Post reset
delay greater than 1000ms are invalid.
