fpga: x4xx: Extend GPIO SPI support

Browse Source 
Extend GPIO SPI transactions up to 64 bits and update the X4xx FPGA
register map and RTL to support the new access width.
Migrate the GPIO SPI register definitions to SystemVerilog.

Add testbench for X4xx GPIO SPI module covering both exisiting
32bit functionality and added 64bit functionality.
Separate TB Makefiles for X4xx and X410 implementation variant.

Bump the FPGA compatibility number so host and MPM software can reject
images that do not provide the required GPIO SPI register interface.
