mb/starlabs/starbook: Fix inclusion of CPU RP ASPM option

The ASPM option for CPU root ports was guarded against the
SOC supporting CPU root ports. This meant that the option
was visible for boards that didn't utilise the CPU root
ports.

Adjust this to guard against BOARD_STARLABS_STARBOOK_RPL,
which is the only board to actually use the CPU root ports.
