Commit 8c966aadcc02 ("fpga: Use device_get_match_data()") dropped the
unconditional use of xlnx_pr_decoupler_of_match resulting in this
warning:

drivers/fpga/xilinx-pr-decoupler.c:94:34: warning: unused variable 'xlnx_pr_decoupler_of_match' [-Wunused-const-variable]

The fix is to drop of_match_ptr() which is not necessary because DT is
always used for this driver.

Hi rob:

Unfortunately I re-applied Commit 8c966aadcc02 and the previous commit
id is lost.

Since the 2 patches are not upstreamed yet, could I just merge them into
one?

Thanks,
Yilun

Looks like altera-ps-spi.c also needs the same fix. Do you mind making
the same change there?
