Add a write_field() function that acts as helper to update specific bits specified in the field defines (FSTV0910_*) in stv0910_regs.h, which was recently updated to carry the missing offset values. With that, add the SET_FIELD(), SET_REG() and GET_REG() macros that wrap the write_field(), write_reg() and read_reg() functions to allow for making all demod access code cleaner. The write_field() function is annotated with __maybe_unused temporarily to silence eventual compile warnings. Picked up from the dddvb upstream, with the macro names made uppercase so they are distinguishable as such.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
