Subject: fpga: region: use image info as parameter for programming region
Use FPGA image info (region->info) when region code is
programming the FPGA to pass in multiple parameters.
This is a baby step in refactoring the FPGA region code to
separate out common FPGA region code from FPGA region
Device Tree overlay support.
