72e224b864 mips: mscc: serval: Fix reset
In case the ddr training was failing, it couldn't reset, it was just
hanging. Therefore reimplement it, so when ddr training is failing
it would call _machine_restart, which power downs the DDR and does
a force reset.

e9f1492bca mips: mscc: luton+ocelot: Remove board config options, do probing
As we are moving to multi-dtb and board detection, remove static board
config options, and introduce board probing instead.

Luton: This add single-binary support for the two MSCC luton-based
reference boards - pcb090 and pcb091. The SoC chip ID is used to
determine the board type.

Ocelot: This add single-binary support for the two MSCC ocelot-based
reference boards - pcb120 and pcb123. The PHY ids on specific ports
are used to determine the board type.
