ARM: dts: aspeed: harma: revise gpio name

Update GPIO label definitions in the device tree to reflect the correct
power and control signal names. This includes:

- Rename "fcb0-activate" to "fcb1-activate" and "fcb2-activate"
- Add labels for:
  - power-p3v3-standby
  - power-p1v8-good
  - power-pvdd33-s5
  - power-pvdd18-s5
  - power-asic-good
  - power-12v-memory-good

- Replace unnamed GPIOs with appropriate labels such as:
  - irq-pvddcore0-ocp-alert
  - irq-pvddcore1-ocp-alert
