mtd: m25p80: Add support for CAT25xxx serial EEPROMs
CAT25 chips (as manufactured by On Semiconductor, previously Catalyst
Semiconductor) are similar to the original M25Px0 chips, except:
- Address width can vary (1-2 bytes, in contrast to 3 bytes in M25P
chips). So, implement convenient m25p_addr2cmd() and m25p_cmdsz()
calls, and place address width information into flash_info struct;
- Page size can vary, therefore we shouldn't hardcode it, so get rid
of FLASH_PAGESIZE definition, and place the page size information
into flash_info struct;
- CAT25 EEPROMs don't need to be erased, so add NO_ERASE flag, and
propagate it to the mtd subsystem.
