refactor(neoverse-rd): rewrite CSS and RoS device mmap macros

The CSS and RoS peripherals memory map macros have incorrect memory base
address and region size values. That is, the existing mmap definitions
are -

  CSS peripherals mmap - Base address (0x20000000) and size (0x20000000)
  RoS peripherals mmap - Base address (0x40000000) and size (0x40000000)

The corrected peripherals memory map definitions are -

  CSS peripherals mmap - Base address (0x20000000) and size (0x40000000)
  RoS peripherals mmap - Base address (0x60000000) and size (0x20000000)

While these macros are being updated, it is a good opportunity to rename
them appropriately. That is, the new macros are named as

  NRD_CSS_PERIPH_MMAP - for mmap macro for CSS peripherals memory region
  NRD_ROS_PERIPH_MMAP - for mmap macro for RoS peripherals memory region
