LPC176X flash_api.h implementation
For LPC176X (LPC1768/LPC1769) the flash driver has been implemented according to the CMSIS-PACK Keil.LPC1700_DFP.2.3.0 driver with the following changes in FlashPrg.c:
1. EraseChip() function removed (not used by flash_api)
2. Clock reconfiguration removed and clock value taken from function parameter to avoid unexpected behavior.
