bindings: net: stmmac: add missing note about LPI interrupt 



The hardware has a LPI interrupt.
There is already code in the stmmac driver to parse and handle the
interrupt. However, this information was missing from the DT binding.

At the same time, improve the description of the existing interrupts.

- interrupt-names: Should contain a list of interrupt names corresponding to

	the interrupts in the interrupts property, if available.

	Valid interrupt names are:

  - "macirq" (combined signal for various interrupt events)

  - "eth_wake_irq" (the interrupt to manage the remote wake-up packet detection)

  - "eth_lpi" (the interrupt that occurs when Tx or Rx enters/exits LPI state)

- phy-mode: See ethernet.txt file in the same directory.

- snps,reset-gpio 	gpio number for phy reset.

- snps,reset-active-low boolean flag to indicate if phy reset is active low.
