This patch changes the large page nand_command() routine to use a word
offset instead of a byte offset. The 'offs' argument gets divided by 2
so that the offset passed to nand_command() is still by byte offset.
Originally, the offset was not shifted and when too high an offset was
requested the nand chip would attempt to read non-existent data.

	    mtd: nand: rearrange ONFI revision checking, add ONFI 2.3

	    In checking for the ONFI revision, the first conditional (for checking
	    "unsupported" ONFI) seems unnecessary.  All ONFI revisions should be
	    backwards-compatible; even if this is not the case on some newer ONFI
	    revision, it should simply fail the second version-checking if-else block
	    (i.e., the bit-fields for 1.0, 2.0, etc. would not be set to 1). Thus, we
	    move our "unsupported" condition after having checked each bit field.

	    Also, it's simple enough to add a condition for ONFI revision 2.3. Note
	    that this does *NOT* mean we handle all new features of ONFI versions
	    above 1.0.

* The sector size for SPI-dataflash (like AT45 flashes) are not always
  a power-of-2. So, the sector calculations are rewritten such that it
  works for either power-of-2 as any size sectors.
* Make the flash sector size optional in case it is the same value as
  the environment size.

There is a bug in the min and max macros in common.h which occurs if
Y is a larger type than X. For example, if Y is a 64-bit value and X
is a 32-bit value then Y will be truncated to 32-bits.  This fix
matches what is done in the Linux kernel but without the additional
type checking present in the kernel version.

This patch adds a new member to struct spi_flash (u16 sector_size)
and updates the spi flash drivers to start populating it.

This parameter can be used by spi flash commands that need to round
up units of operation to the flash's sector_size.

Having this number in one place also allows duplicated code to be
further collapsed into one common location (such as erase parameter
and the detected message).
