[PATCH v12 03/13] fpga: xilinx: add bitstream flags to driver desc

[Oleksandr Suvorov]

Store a set of supported bitstream types in xilinx_desc structure.
It will be used to determine whether an FPGA image is able to be
loaded with a given driver.

(no changes since v10)

Changes in v10:
- move FPGA flags to macros;
- initialize xilinx_desc structs directly, removing *_DESC macros;
- initialize flags for mach-zynq;
