mtd: docg3 fixes backport from Linux kernel ...

Backport 2 fixes back from Linux kernel (title verbatim from
Linux kernel log) :
 - docg3 fix in-middle of blocks reads
 - docg3 reduce read alignment burden

These 2 enable partial reads from the MTD (ie. read only the
111 first bytes), which enable linux kernel booting or UBIFS
from barebox.

mci: pxamci poweron ramp delay ...

As per MMC spec, once power has been applied to an SD card, the card
can take as much as 250ms to complete its power-up cycle, and become
responsive to CMD0.

When this delay was not in place, activating the SD card in the env
init failed sometimes. With it, no more failure are observed.

mci: pxamci fix R1b responses ...

The pxamci driver was not waiting for the BUSY line to be
deasserted. This was specifically breaking the CMD12 at
the end of block multiple writes, when the SD card had not
time enough to commit the last write.

Fix it by waiting for PRG_DONE bit (which is actually the
busy signal end condition).

cfi flash: Fix alignment problem ...

The intel cfi buffer write has a problem with writing when
the alignment of the buffer in memory is smaller than the
flash bus width.

This patch fixes a alignment problem which may show during this
scenario:
- 32 or 64 attached NOR flash
- flashing an image directly from network to the nor flash

The involved network driver is "smc9111.c".

The data that comes from the network stack and should be written into
the flash isn't 32 bit aligned (at least with this network driver).
This is probably due to the 48 bit wide ethernet addresses.

However the "cfi_flash.c" driver doesn't handle this situation, and
accesses the not-aligned address with a 32 bit pointer.

This patch fixes the problem by reducing the access width if an
aligment problem between source and destination is found.
