refactor(neoverse-rd): refactor mmap macro for RoS device memory region

There are two macros that define ROS device memory map range and
attributes - one for local chip and the other for remote chip. Refactor
these two macros into a single macro that uses the chip ID to identify
the local or the remote chip.
