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.
