Subject: [PATCH v2] fpga: allow to compile-test Altera FPGA bridge drivers

Add COMPILE_TEST to the Kconfig entry for the Altera SoCFPGA FPGA
Bridge. The Altera FPGA Freeze Bridge can also be used on Altera PEIe
FPGAs, so the driver shouldn't depend on ARCH_SOCFPGA in the first place.
This allows test-compiling the drivers on other architectures to catch
compiler errors/warnings, e.g. due to API/header changes earlier on.
