I guess that would work.

However, I'd suggest simply leaving all the SoC-specific stuff in the
SoC-specific files until it actually becomes shared. Otherwise, you're
simply putting all the code into one big file, and parameterizing it to
get the correct SoC-specific clocks registered, when you could just keep
the SoC-specific code in the SoC-specific file/functions, and not need
any of the conditions.
