[PATCH v2] ARM: dts: aspeed: sanmiguel: Disable HSC nodes

[Potin Lai]

Disable Hot-Swap Controller (HSC) power monitor nodes in the DTS.

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

Signed-off-by: Potin Lai <potin.lai.pt at gmail.com>

Changes in v2:
- Set the HSC nodes status disabled instead of removing.
- Link to v1: https://patch.msgid.link/20260730-upstream-sanmiguel-remove-hsc-nodes-v1-1-f0308eb8a00c@gmail.com
