[LPC812] enable SPISlave
fix - KL46Z cmsis header (v2.2), shared interrupt PORTCD

	- Ports C and D sharing same interrupt vectors
	- KL46Z CMSIS header update
	- InterruptIn methods irq_disable/enable comment update
Shared PORT interrupt - check improved

	- clocks must be enabled and also interrupt detected, otherwise
	  interrupt handler is not invoked.

Added Sleep, LED3 and LED4 definitions, switches

Sleep = KL25Z sleep (verified to work correctly)
LED3 = LED1, LED4 = LED2 (for compatibility, similar to LED3 = LED4 in
KL25Z code)
SW1 and SW3 for the two switches (SW2 is reset switch)
Fixed KL25Z SPI clock
