lpc32xx: Flash driver

Browse Source 
Based on the lpc3180 driver, but released as a separate driver for two reasons:
 1) I don't have an lpc3180 to test it against, so it might unintentionally break compatibility.
 2) It's using a different OOB layout than lpc3180.

Rewritten so that it no longer borrows code from the NXP CDL library.  Instead borrowing code from the u-boot port to lpc32xx, written by Kevin Wells.

Tested on lpc3250 (Hitex LPC3250-Stick).  OOB layout is compatible with LPCLinux.
