arm64: dts: mediatek: cherry: Specify pull resistance for RSEL GPIOs
GPIOs 34 and 35 on MT8195 are of type MTK_PULL_PU_PD_RSEL_TYPE, meaning
not only can they be configured as pull-up or pull-down, but the pull
resistance can also be configured.

The current bias setting however doesn't specify a resistance value,
resulting on the following errors:

mt8195-pinctrl 10005000.pinctrl: Not support rsel value 1 Ohm for pin = 34 (GPIO34)
mt8195-pinctrl 10005000.pinctrl: Not support rsel value 1 Ohm for pin = 35 (GPIO35)

Specify the pull resistance for those GPIOs to fix the errors.
