[PATCH] ARM: dts: aspeed: sanmiguel: Remove HSC nodes

Remove Hot-Swap Controller (HSC) power monitor nodes from the DTS.

Due to design requirements, the HSC driver probing is moved to userspace.
Removing these nodes from the device tree prevents kernel-level automatic
driver probing and allows userspace to handle HSC device instantiation.
