nvmem: NXP LPC18xx EEPROM memory NVMEM driver
This commit adds support for NXP LPC18xx EEPROM memory found in NXP LPC185x/3x and LPC435x/3x/2x/1x devices. EEPROM size is 16384 bytes and it can be entirely read and written/erased with 1 word (4 bytes) granularity. The last page (128 bytes) contains the EEPROM initialization data and is not writable. Erase/program time is less than 3ms. The EEPROM device requires a ~1500 kHz clock (min 800 kHz, max 1600 kHz) that is generated dividing the system bus clock by the division factor, contained in the divider register (minus 1 encoded). EEPROM will be kept in Power Down mode except during read/write calls.
