[PATCH 4/5] ARM: dts: microchip: sam9x7: Remove the tx_clk from gmac node

The gmac controller on sam9x7 has no internal pll to generate
the 125MHz clock source for rgmii mode.
This clock is generated on external board by eth-phy or
clock oscillator.
This change drops the tx_clk entry from gmac node.
