arm64: dts: mt8192: Follow binding order for SCP registers

The dt-binding for SCP documents the reg-names order as sram, cfg,
l1tcm. Update the SCP node on the mt8192 devicetree to follow that
order, which gets rid of a dtbs_check warning. This doesn't change any
behavior since the SCP driver accesses the memory regions through the
names anyway.
