ARM: dts: zynq: Enable PL clocks for Parallella
commit 92c9e0c780e61f821ab8a08f0d4d4fd33ba1197c upstream. The Parallella board comes with a U-Boot bootloader that loads one of two predefined FPGA bitstreams before booting the kernel. Both define an AXI interface to the on-board Epiphany processor. Enable clocks FCLK0..FCLK3 for the Programmable Logic by default. Otherwise accessing, e.g., the ESYSRESET register freezes the board, as seen with the Epiphany SDK tools e-reset and e-hw-rev, using /dev/mem.
