[PATCH 3/3] ARM: dts: bcm2711: give the GENET MDIO controller its clock

[Nicolai Buchwitz]

The MDC of the GENET MDIO controller comes from the GISB clock.
Describe it, so mdio-bcm-unimac can get the real 200 MHz from
clk_get_rate() instead of assuming the 250 MHz of the STB chips, and
can put bounds on when an MDIO write completes for PTP.
