realtek: update GPIO bindings in the dts files in dts-5.10

this patch includes the following changes:

- adjust mapping for the new driver
  - GPIO 24 -> GPIO 0
  - GPIO 47 -> GPIO 0 (+ disabling system LED)

- disable pins in the invalid range
  (out of the range 0-31 of the new driver)
  - are these pins on the external RTL8231 (&gpio1)?
    - GPIO 67 (-> GPIO 3 on &gpio1?)
    - GPIO 94 (-> GPIO 30 on &gpio1?)

- drop "indirect-access-bus-id" property from gpio0 node in device dts
  files
