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.

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
