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.

+NXP's LPC43xx and LPC18xx families include a proprietary SPI
+Flash Interface (SPIFI) peripheral that can drive and provide
+memory mapped access to external SPI flash devices.
+
+The lpcspifi driver initializes this interface and provides
+program and erase functionality for these serial flash devices.
+Use of this driver @b{requires} a working area of at least 1kB
+to be configured on the target device; more than this will
+significantly reduce flash programming times.
+
+The setup command only requires the @var{base} parameter. All
+other parameters are ignored, and the flash size and layout
+are configured by the driver.
