Subject: net: stmmac: Fallback to Platform Data clock in Watchdog conversion

[ Upstream commit 4ec5302fa906ec9d86597b236f62315bacdb9622 ]

If we don't have DT then stmmac_clk will not be available. Let's add a
new Platform Data field so that we can specify the refclk by this mean.

This way we can still use the coalesce command in PCI based setups.
