dfe64e2c89 mtd: resync with Linux-3.7.1
This patch is essentially an update of u-boot MTD subsystem to
the state of Linux-3.7.1 with exclusion of some bits:

- the update is concentrated on NAND, no onenand or CFI/NOR/SPI
flashes interfaces are updated EXCEPT for API changes.

- new large NAND chips support is there, though some updates
have got in Linux-3.8.-rc1, (which will follow on top of this patch).

To produce this update I used tag v3.7.1 of linux-stable repository.

The update was made using application of relevant patches,
with changes relevant to U-Boot-only stuff sticked together
to keep bisectability. Then all changes were grouped together
to this patch.

253f47f3a7 Blackfin: bfin_nand: convert to portmux framework
Rather than bang MMRs directly, use the new portmux framework to handle
the details.

c941b77adc Blackfin: nand: drain the write buffer before returning
The current Blackfin nand write function fills up the write buffer but
returns before it has had a chance to drain.  On faster systems, this
isn't a problem as the operation finishes before the ECC registers are
read, but on slower systems the ECC may be incomplete when the core tries
to read it.

So wait for the buffer to drain once we're done writing to it.

a343ba87ea Blackfin: nand: flush peripheral before polling it
We need to make sure the data written to the nand flash controller makes
it there before we start polling its status register.  Otherwise, we may
get stale data and return before the controller is actually ready.
