Most of the drivers only support a subset of {PARTIAL, FULL}
reconfiguration.
Pull duplicate checks in each driver into the framework.

Hi all,
with the new drivers (ice40, altera-ps-spi) being submitted I've noticed
we're duplicating this check over and over again,
so I figured we might as well pull it into the framework.
I'm not sure if there are gonna be other 'flags' we need to support
in the short term (we talked about byte-swapping ...)
Note: This patch goes on top of greg's char-misc-testing that already
contains Alan's latest changes to support the A10 and won't apply
to master.
Cheers,
Moritz

Found a couple of issues, will resubmit after cleaning up. Feel free to add
general feedback on the idea anyways in the meantime. Sorry for double post.

On second thought the FULL_RECONFIG is the same as !PARTIAL_RECONFIG,
so useless ..

Hi Moritz,
This looks good and useful to me. One comment below.

That looks good and doesn't seem useless to me. A driver may
support PR, FR, or both. It's nice and clear what
FPGA_MGR_PARTIAL_RECONFIG|FPGA_MGR_FULL_RECONFIG means when
a driver supports both.
