mtd: flash drivers set ecc strength
Flash device drivers initialize 'ecc_strength' in struct mtd_info, which is the
maximum number of bit errors that can be corrected in one writesize region.
Drivers using the nand interface intitialize 'strength' in struct nand_ecc_ctrl,
which is the maximum number of bit errors that can be corrected in one ecc step.
Nand infrastructure code translates this to 'ecc_strength'.
Also for nand drivers, the nand infrastructure code sets ecc.strength for ecc
modes NAND_ECC_SOFT, NAND_ECC_SOFT_BCH, and NAND_ECC_NONE. It is set in the
driver for all other modes.

mtd: do not use plain 0 as NULL
The first 3 arguments of 'mtd_device_parse_register()' are pointers,
but many callers pass '0' instead of 'NULL'. Fix this globally. Thanks

mtd: convert drivers/mtd/* to use module_platform_driver()
This patch converts the drivers in drivers/mtd/* to use the
module_platform_driver() macro which makes the code smaller and a bit
simpler.

mtd: jz4740_nand.c: use mtd_device_parse_register
Replace custom invocations of parse_mtd_partitions and mtd_device_register
with common mtd_device_parse_register call. This would bring: standard
handling of all errors, fallback to default partitions, etc.

mtd: jz4740_nand don't specify default parsing options
Since 'cmdline, NULL' is now a default for parse_mtd_partitions, don't specify
this in every driver, instead pass NULL to force parse_mtd_partitions
to use default.

mtd: NAND: jz4740: Remove custom {read,write}_page handlers
Now that the mtd core supports more then 64 ecc bytes we can use it instead of
some a custom hack in the jz4740 nand driver.
This patch removes the custom {read,write}_page handlers from the jz4740 nand
driver. Thus the driver will now fallback to the default handlers from the nand
core.
