Currently the reset vector address is hard-coded in a RISC-V CPU's
instance_init() routine. In a real world we can have 2 exact same
CPUs except for the reset vector address, which is pretty common in
the RISC-V core IP licensing business.

Normally reset vector address is a configurable parameter. Let's
create a 64-bit property to store the reset vector address which
covers both 32-bit and 64-bit CPUs.
