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.
