net: ethernet: ti: cpts: add support for ext rftclk selection
Some CPTS instances, which can be found on KeyStone 2 1G Ethernet Switch Subsystems, can control an external multiplexer that selects one of up to 32 clocks as time sync reference (RFTCLK) clock. This feature can be configured through CPTS_RFTCLK_SEL register (offset: x08) in CPTS module and can be represented as multiplexer clock. Hence, introduce support for optional cpts-refclk-mux clock, which, once defined will allow to select required CPTS RFTCLK by using assigned-clock-parents DT property in board files.
