[PATCH 1/2] net: ethernet: stmmac: demote warnings about missing optional clocks

[Ahmad Fatoum]

The specification of a "eth-ck" and a "ptp_ref" clock is optional per
the binding and the driver handles them gracefully.
Demote the output to an info message accordingly.

[PATCH 2/2] net: ethernet: stmmac: don't warn about missing optional wakeup IRQ

[Ahmad Fatoum]

The "stm32_pwr_wakeup" is optional per the binding and the driver
handles its absence gracefully. Request it with
platform_get_irq_byname_optional, so its absence doesn't needlessly
clutter the log.
