devm_ioremap_resource does sanity checks on the given resource. No need to
duplicate this in the driver.

This patch adds support for subpage (partial-page) writes when using
hardware based ECC schemes.
Advantages:
(1) reduces storage overhead when using file-systems like UBIFS, which
store LEB header at page-size granularity.
(2) allows independent subpage writes, thereby increasing NAND storage
efficiency for non-page aligned data.
+ updated cafe_nand and lpc32xx_mlc NAND drivers for change in
chip->write_page interface.

Convert all uses of devm_request_and_ioremap() to the newly introduced
devm_ioremap_resource() which provides more consistent error handling.

devm_ioremap_resource() provides its own error messages so all explicit
error messages can be removed from the failure code paths.

The LPC32xx's DT-only conversion of the MLC NAND driver makes NAND config via
platform_data obsolete. Dropped by this patch.

Further, the driver really needs CONFIG_OF, which is already reflected by the
dependency on ARCH_LPC32XX which depends on CONFIG_OF. So also dropping
CONFIG_OF ifdefs.

There is still platform_data necessary to supply the dma_filter callback for
the dma engine. This is a completely different data structure than the old
platform_data for NAND config, so renaming some old "pdata" variable to "ncfg"
to prevent confusion with the new platform data.

This patch makes the MLC NAND driver independent of the single AMBA DMA engine
driver by using the platform data provided dma_filter callback.
