Activated the I2CSlave functions. Slave block read/write operations are fully supported. The slave byte read and writes need general modification to I2CSlave.cpp. See pending Issue.
Activated the PWM functions. They are supported now using the SCT after updating us_ticker() to use the MRT instead of the SCT.
There were lots of overlaps in the code for LPC810 and LPC812, including
duplicated source files. This commit adds a TARGET_LPC81X_COMMON folder in
both HAL and CMSIS, this folder keeps common code for the targets.
