arm64: zynqmp: Enable usb3 for k24 som

This patch corrects the mio and pll configuration registers for using usb3
on the kd240 starter kit.  Without this patch, the usb3 to sd card bridge does
not initialize correctly and u-boot is unable to find the OS located on the
kd240 starter kit sd card.

In addition, this patch correctly configures mio76 and mio77 as gpio pins
which are used as reset gpio pins on the kd240 starter kit.
