boards: riscv: rv32m1: enable BT related configuration

Specific SW defined BLE LL parameters need to be set
if the user enables it on this platform. As such, conditionally
enable them directly into the defconfig.

INTMUX CH2 and CH3 are not available to be used if BT support
is enabled on Vega, because they are used internally by the
BLE SW LL
