Subject: [PATCH] arm64: zynqmp: Fix k24 psu_init_gpl.c clocking
This patch corrects the k24 som clocking configuration such that the serdes
clocks are correctly enabled and the usb0 is configured to use the psgtr
refclk2 for usb3 mode.
This patch also corrects the configuration of mio pins mio76 and mio77
which should be configured as gpio pins.
