net: stmmac: dwmac-stm32: Extract PMCR configuration
Pull the PMCR clock mux configuration into a separate function. This is the final change of three, which moves external clock rate validation, external clock selector decoding, and clock mux configuration into separate functions. This should make the code easier to understand. No functional change intended.
