Subject: [PATCH AUTOSEL 5.4 160/205] ARM: dts: dra7: fix cpsw mdio fck clock

From: Grygorii Strashko <grygorii.strashko@...com>

[ Upstream commit 6af0a549c25e0d02366aa95507bfe3cad2f7b68b ]

The DRA7 CPSW MDIO functional clock (gmac_clkctrl DRA7_GMAC_GMAC_CLKCTRL 0)
is specified incorrectly, which is caused incorrect MDIO bus clock
configuration MDCLK. The correct CPSW MDIO functional clock is
gmac_main_clk (125MHz), which is the same as CPSW fck. Hence fix it.
