soc: rockchip: grf: Add rk3576 default GRF values

Browse Source 
Set SW controlled i3c weak pull up and disable JTAG function on SDMMC IO.

The i3c weak pull up is activated to let all gpio banks be controlled
by the pinctrl driver.

Disabling the JTAG function lets the SDMMC core use its full IO width.
