[PATCH 2/2] ARM: dts: rockchip: rk3288: Remove rockchip,grf from tsadc

According to rockchip-thermal.yaml, RK3288 does not require rockchip,grf,
so remove this invalid property.

This fixes the following dt-schema warning:

tsadc@ff280000 (rockchip,rk3288-tsadc): False schema does not allow [[53]]

The rockchip_thermal driver also confirms that grf is not needed as
the rk3288_tsadc_data contains:
 .grf_required = false,
