This patch adds support for the ADC, LCD, USB gadget and PWM controllers to the
at91sam9rl. It also reorders the pinctrl_spi0 as it was not correctly sorted.

This adds support for:
- SPI
- Dataflash
- LCD
- i2c
- ADC
- Touchscreen
- USB gadget
- PWM
Also it switches the ds1 and ds2 leds to PWM control.
