mtd: nand: extend NAND flash detection to new MLC chips ...

Some of the newer MLC devices have a 6-byte ID sequence in which
several field definitions differ from older chips in a manner that is
not backward compatible.

This method is already used in the Linux Kernel.

mtd nand: implement buswidth detection ...

This introduces a new NAND_BUSWIDTH_AUTO flag which can be used
to automatically detect the nand buswidth. The id is always read
in 8bit mode. An additional callback is needed to switch the nand
controller into 16bit mode.
This currently depends on a safe read_byte (always) and read_buf
(for onfi-only flashes) callback. It has been tested on OMAP, but
is not something that generally works. For this reason the existence
of the set_buswidth callback is used to determine whether we are
able to do autodetection or not.

mtd OMAP NAND: Fix dev_ready handling ...

- dev_ready is supposed to return whether the device is ready or
  not, not to poll until the device is ready.
- dev_ready should return true for ready and false for not ready
- waitpin polarity is not needed (at least the kernel does not have it)
- wait_mon_mask must be 32bit.

The code was unused since no board specified a wait pin, so no breakage
included. This also removes the now unused timeout variable from
platformdata.
