[PATCH 2/2] ARM: dts: aspeed: sanmiguel: add current-range property for PDB HSC

Configure the ti,current-range property for the four TI LM5066i
hot-swap controllers on PDB board.

This defines the hardware current limit operating mode (low/high)
for each sensor to match the physical board design.

Specific configurations:
- HSC1 (0x11): low
- HSC2 (0x13): high
- HSC3 (0x15): high
- HSC4 (0x17): low
