spec/build/riscv: Default rv64* BSPs to medany cmodel

Currently generic RISC-V BSPs (riscv/riscv) that start with rv64 and not
rv64*_medany will start at 0x70000000. This adds high maintenance overhead
and deviates from almost all other RISC-V-based OSes and baremetal programs
that start at 0x80000000. Further, testing now has to account for an extra
parameter (medany or not) that doubles the number of BSPs need to be
tested.

This commit defaults all RV64 BSPs to use medany code model to allow starting
all BSPs at 0x80000000. BSPs that require different code models and/or
start addresses are custom and need to add their own entries.

Updates #4775
