Udelay function might get delay less than the time indicated by the
input parameter. udelay(4) sometimes get the tick like, 6->7->7->
8->8->9->A and then the udelay return. But, the sampling point of 6
could be at the end of 6(close to 7) and the point of A could be
right at the beginning of A(close to A). This function could get
delay from (us - 1) to (us + 1). This change is to ensure the delay
at least over the parameter, us.

TEST=Build an EC FW iamge and run on Rambi to ensure at the time

This make minor syntactic changes and renames some camel-cased symbols
to keep checkpatch from complaining. The goal is to reduce the
temptation to use 'repo upload --no-verify'.
This is a big furball of find/replace, but no functional changes.
