Subject: [PATCH v3 09/10] ARM: dts: aspeed: system1: Mark GPIO line high/low

- Mark following GPIO lines as input high:
  - GPIOL4 (reset PCH registers)
  - GPIOL5 (reset portition of intel ME)
- Mark isolate errors from cpu1 gpio (GPIOO6) as active low output.
- The fan controller reset line should be active high.
