Add get_flash_bank_by_name (and get_nand_device_by_name) helpers to retrieves struct flash_bank * (struct nand_device *) given a driver name and an (optional) driver-specific bank index. These are used to extend flash_command_get_bank_by_num (and nand_command_get_device_by_num) to allow all flash (nand) commands to reference defined banks by name, not just by number. To avoid some code duplication, add the flash/common.[ch] files to hold functionality common to both types driver. The first two methods are helpers for the above routines to find a bank specified by a "name" or "name.index" string. get_flash_name_index() finds the '.index' portion, while flash_driver_name_matches() performs the string portion matching.
