[PATCH v2 10/11] fpga: Add flag to indicate bitstream needs decompression

[Alan Tull <atull@kernel.org>]

From: Anatolij Gustschin <agust@denx.de>

Add a flag that is passed to the write_init() callback, indicating
that the bitstream is compressed.

The low-level driver will deal with the flag, or return an error,
if compressed bitstreams are not supported.
