PCI: xilinx: Drop obsolete dependency on COMPILE_TEST

Since commit 0166dc11 ("of: make CONFIG_OF user selectable"), it is
possible to test-build any driver which depends on OF on any architecture
by explicitly selecting OF. Therefore depending on COMPILE_TEST as an
alternative is no longer needed.
