fpga: Use device_get_match_data()
Use preferred device_get_match_data() instead of of_match_device() to
get the driver match data. With this, adjust the includes to explicitly
include the correct headers.
Also drop of_match_ptr for xlnx_pr_decoupler_of_match, which is not
necessary because DT is always used for this driver.
