net: stmmac: move reverse-"pcs" mode setup to stmmac_check_pcs_mode()

Browse source

The broken reverse-mode, selected by snps,ps-speed, is configured when
the platform provides a valid port speed and a PCS is being used.

Both these remain constant after the driver has probed, so the software
state doesn't need to be re-initialised each time stmmac_hw_setup() is
called (which is called at open and resume time.)

Move the software setup of reverse-mode to stmmac_check_pcs_mode()
which is called from the driver probe function.
