soc/cavium: Apply additional devicetree fixups
Depends on Change-Id: I0f27b92a5e074966f893399eb401eb97d784850d Apply additional devicetree fixes: * Update SCLK from boot fuses * Updated REFCLKUAA from UART ref clock divider settings * Remove disabled PEM entries * Remove phandle to disabled PEM entries Fixes: * Linux console wrong baud rate once the PL011 driver is started. * thunderx-pem kernel module crash on disable PCIe ports. Tested on Cavium SoC.
