flashchips: change chip name from 'W25Q64JW' to 'W25Q64JW...M'

According to the W25Q64JW datasheet rev. E, only devices ending with the
letter 'M' have a device ID of 8017h. There are other variants with
different device IDs. This patch makes the 'W25Q64JW...M' definition
consistent with the 'W25Q32JW...M' definition.

The device ID macro defined in flashchips.h has also been renamed from
WINBOND_NEX_W25Q64JW to WINBOND_NEX_W25Q64JW_M.
