Added SPIFI flash driver, algorithms, and docs
Added a flash driver designed to allow program/erase of memory-mapped SPI flash chips for LPC43xx/LPC18xx family micros. This driver includes three algorithms - erase, write, and SPIFI peripheral initialization (to allow memory-mapped access after a reset). The driver has been added to the flash driver table (drivers.c), and the OpenOCD documentation has been updated to include the flash driver configuration command.
