Subject: [PATCH v2 2/4] ARM: dts: s5pv210: aries: Support for more devices present on Aries

From: Jonathan Bakker <xc-racer2@...e.ca>

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)
