The eLBC NAND driver currently follows up each program/write operation with a
read-back of the page, in order to [ostensibly] fill in ECC data for the
caller. However, the page address used for this read is always -1, so the read
will never work correctly. Remove this useless (and potentially problematic)
block of code.

mxc_nand: fix a problem writing more than 32MB
When writing 0x4000 to the unlockend_blkaddr register, large writes to
a 2k page NAND sometimes fail. The current kernel driver writes 0xFFFF
to this register for V2 of the nand controller.
However on an i.MX31 this also fixes writes larger than 32MB.
The datasheet is very unspecific, but (0x4000=16384)*2000
roughly fits the limits we're encountering with NAND writes.
This problem might be NAND chip specific.

Turn on the watchdog WDZST bit so that watchdog timer does not count during low power modes.
Prior to applying this patch mx31pdk board got watchdog resets because when it booted in the Linux prompt
and there was no activity, the system entered into idle mode while watchdog timer was still active.
Fix this by disabling watchdog timer during idle mode.
Once the MDIO state machine has been initialized and enabled, it
starts polling all 32 PHY addresses on the MDIO bus, looking for
an active PHY. Add a 5 ms delay, so all PHYs are for sure detected.
