NAND datasheets usually give the maximum number of bad blocks per LUN
and this number can be used to help upper layers decide how much blocks
they should reserve for bad block handling.
Add a max_bad_eraseblocks_per_lun to the nand_memory_organization
struct and update the NAND_MEMORG() macro (and its users) accordingly.
We also provide a default mtd->_max_bad_blocks() implementation.

The datasheet specifies the upper four bits are reserved.
Testing on real hardware shows that these bits can indeed be nonzero.

MX35LF2GE4AB is almost identical to MX35LF1GE4AB except it has 2 times
more eraseblocks per LUN and exposes 2 planes instead of 1.

Add minimal support for the MX35LF1GE4AB SPI NAND chip.
