Change how patches are applied to reduce redundancy and make the code
more readable. Define a generic function that applies any patch. Within
the RTL930x patch application, define a local macro that helps to get
rid of repeated even/odd checks. While making the code cleaner, it is
also a preparation for further refactoring here.
This adds a local helper macro intended to be only temporary but keeps
the style of the code clean by avoiding a lot of if-else clauses.
