this patch is based on linux master branch, implementation as following:
- add the i2c pinctrl which needed for using at91sam9n12 TWI
- enable qt1070
- trivial fix for the gpio-key pin number

arm: atmel: at91sam9n12: add pinctrl of TWI
arm: atmel: at91sam9n12: add qt1070 support
arm: atmel: at91sam9n12: correct pin number of gpio-key
