This patch series converts the i2c-qup bindings to YAML and then
adds support for noise rejection, which is needed for some noisy
hardware, like the touchscreen on the F(x)Tec Pro1.
After adding noise rejection, the touchscreen stopped showing
ghost touch issues and lockups.

Tested on F(x)Tec Pro1 (MSM8998).

Changes in v2:
- Fixed ARM (32) build error (added bitfield.h inclusion)

i2c: qup: Introduce SCL/SDA noise rejection
