Pull ARM SoC fixes from Olof Johansson:
 "Another quiet week:

   - a fix to silence edma probe error on non-supported platforms from
     Arnd
   - a fix to enable the PL clock for Parallella, to make mainline
     usable with the SDK.
   - a somewhat verbose fix for the PLL clock tree on VF610
   - enabling of SD/MMC on one of the VF610-based boards (for testing)
   - a fix for i.MX where CONFIG_SPI used to be implicitly enabled and
     now needs to be added to the defconfig instead
   - another maintainer added for bcm2835: Lee Jones"

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.
