NAND FSL UPM: driver re-write using the hwcontrol callback

This is a re-write of the NAND FSL UPM driver using the more universal
hwcontrol callback (instead of the cmdfunc callback). Here is a brief
list of furher modifications:

- For the time being, the UPM setup writing the UPM array has been
removed from the driver and must now be done by the board specific
code.

- The bus width definition in "struct fsl_upm_nand" is now in bits to
comply with the corresponding Linux driver and 8, 16 and 32 bit
accesses are supported.

- chip->dev_read is only set if fun->dev_ready != NULL, which is
required for boards not connecting the R/B pin.

- A few issue have been fixed with MxMR bit manipulation like in the
corresponding Linux driver.

Note: I think the "io_addr" field of "struct fsl_upm" could be removed
as well, because the address is already determined by
"nand->IO_ADDR_[RW]", but I'm not 100% sure.

This patch has been tested on a TQM8548 modules with the NAND chip
Micron MT29F8G08FABWP.

This patch is based on the following patches posted to this list a few
minutes ago:

PPC: add accessor macros to clear and set bits in one shot
83xx/85xx/86xx: add more MxMR local bus definitions

Big white-space cleanup.

This commit gets rid of a huge amount of silly white-space issues.
Especially, all sequences of SPACEs followed by TAB characters get
removed (unless they appear in print statements).

Also remove all embedded "vim:" and "vi:" statements which hide
indentation problems.
