include: fpga: adi-axi-common.h: add common regs & defs header

Browse Source 
The AXI HDL cores provided for Analog Devices reference designs all share
some common base registers (e.g. version register at address 0x00).

To reduce duplication for this, a common header is added to define these
registers as well as bitfields & macros to work with these registers.
