arm64: dts: rockchip: Fix broken tsadc pinctrl names for rk3588

The tsadc driver does not handle pinctrl "gpio" and "otpout".
Let's use the correct pinctrl names "default" and "sleep".
Additionally, Alexey Charkov's testing [1] has established that
it is necessary for pinctrl state to reference the &tsadc_shut_org
configuration rather than &tsadc_shut for the driver to function correctly.
