soc/intel/{skl,cnl,icl}: Drop soc_uart_set_legacy_mode()
This is never called: The only calling path is guarded by both
!DRIVERS_UART_8250MEM_32 and INTEL_LPSS_UART_FOR_CONSOLE but the
latter selects the former.
If somebody figures out how this is supposed to be used, we can
easily revive the implementation.
