Subject: [PATCH] fpga: xilinx-pr-decoupler: Fix unused xlnx_pr_decoupler_of_match warning for !CONFIG_OF

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.
