the 2Gb version has twice as many blocks and therefore the maximum
number of bad blocks is 40.
The 4Gb GigaDevice GD5F4GQ4xA has twice as many blocks as its 2Gb
counterpart and therefore a maximum of 80 bad blocks.

The GigaDevice GD5F1GQ4UFxxG SPI NAND is in current production devices
and, while it has the same logical layout as the E-series devices,
it differs in the SPI interfacing in significant ways.
This support is contingent on previous commits to:
* Add support for two-byte device IDs
* Define macros for page-read ops with three-byte addresses

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.

Looks like PROGRAM LOAD (AKA write cache) does not necessarily reset
the cache content to 0xFF (depends on vendor implementation), so we
must fill the page cache entirely even if we only want to program the
data portion of the page, otherwise we might corrupt the BBM or user
data previously programmed in OOB area.
