ipq40xx: re-enable MeshPoint.One target

ipq40xx: re-enable MeshPoint.One target

The MeshPoint.One was disabled during the DSA migration with the
comment "Missing DSA Setup". However, this device inherits its
entire network configuration from 8dev Jalapeno via the
Device/8dev_jalapeno-common template, and shares the same DSA
network setup in 02_network.

The Jalapeno has been working with DSA since the migration. All
MeshPoint.One board support files (DTS, network config, LED config)
are already in place and reference the same QCA8072 switch
configuration as the Jalapeno.

Hardware: Qualcomm IPQ4018, QCA8072 switch, same as 8dev Jalapeno.
Tested: Built firmware from current main branch, boots and network
functions correctly.
