Some I2C devices may be glitchy due to electrical noise coming
from the device itself or because of possible board design issues.
To overcome this issue, the QUP's I2C in Qualcomm SoCs supports
a noise rejection setting for both SCL and SDA lines.
Introduce a setting for noise rejection through device properties,
"qcom,noise-reject-sda" and "qcom,noise-reject-scl", which will
be used to set the level of noise rejection sensitivity.
If the properties are not specified, noise rejection will not be
enabled.
