[MTD] [NAND] pxa3xx_nand: allow to define flash types in the platform data
This patch adds 'flash' and 'num_flash' attributes to the platform data.
There was added code in the driver to iterate across these attributes in the
detect-flash routine. This is done similarly to the existing method
which uses a 'builtin_flash_types' field.
