arm: socfpga: fpga: Add SoCFPGA FPGA programming interface
Add code necessary to program the FPGA part of SoCFPGA from U-Boot
with an RBF blob. This patch also integrates the code into the
FPGA driver framework in U-Boot so it can be used via the 'fpga'
command.

V2: Move the not-CPU specific stuff into drivers/fpga/ and base
this on the cleaned up altera FPGA support.
