From: Jonathan Bakker <xc-racer2@xxxxxxx>
This commit enables following devices present on Aries based phones:
- pwm-vibrator attached to PWM 1
- poweroff support
- Atmel maXTouch touchscreen, connected to i2c2
- Broadcom BCM4329 bluetooth over uart0

Changes from v1:
- Touchscreen irq pin should have PULL_NONE, since it's already
pulled up with 2.8v
- Touchscreen irq should be edge failing (like in vendor sources)
