TSD: arm64: dts: rockchip: enable internal pull-ups for Q7_SDIO_WP and Q7_SMB_ALERT
Each of the above mentioned pins is connected to a diode
on the module which is used as a level shifter, and they
are configured internally pulled-down by default.
We need to configure these pins to internally pulled-up,
otherwise whenever one of the pins is configured as INPUT
and we try to control it externally the value will always
remain zero.
[TSD] Only applies to Haikou Tester as those pins aren't
necessarily used as input so we don't need to always have
a pull-up for it (e.g. if driving them as output).
[TSD] No upstream Haikou Tester support for now
Relates-to: PUMA-90, PUMA-91
