VeeR defines uniquification

[nstewart-amd]

VeeR defines must be uniquified to avoid collision/redefinition when multiple VeeR cores are instantiated in a single design.

Since verilog macro defines are global namespace, they must be uniquified to avoid macro redifinition collision against other common IP names and multi-VeeR usercases.

The following are generic and subject to contention:

common_defines.vh
define REGWIDTH 32 define CLOCK_PERIOD 100
`define TOP tb_top

el2_param.vh
Most everything.
From a generic perspective, VeeR users should be able to integrate mutliple Veer configurations in parallel without collision.
Hence, anything "defined" in {veer.config -default} must not collide with defines in {veer.config -high_perf}.
Defines must be uniquified allowing multiple concurrent instantiation of differently configured VeeR cores.

Today:
`define FOO 0x1

Recommended
VeeR default config: `define VEER_default_FOO 0x1
Veer high_perf config: `define VEER_high_perf_FOO 0x2
