pinctrl: meson: define the pull up/down resistor value as 60 kOhm
The public datasheets of the following Amlogic SoCs describe a typical
resistor value for the built-in pull up/down resistor:
- Meson8/8b/8m2: not documented
- GXBB (S905): 60 kOhm
- GXL (S905X): 60 kOhm
- GXM (S912): 60 kOhm
- G12B (S922X): 60 kOhm
- SM1 (S905D3): 60 kOhm
The public G12B and SM1 datasheets additionally state min and max
values:
- min value: 50 kOhm for both, pull-up and pull-down
- max value for the pull-up: 70 kOhm
- max value for the pull-down: 130 kOhm
Use 60 kOhm in the pinctrl-meson driver as well so it's shown in the
debugfs output. It may not be accurate for Meson8/8b/8m2 but in reality
60 kOhm is closer to the actual value than 1 Ohm.
