rockchip: rk3399-roc-pc: Hook sysreset gpio to enable full reset
The reset mechanism used by Linux to reset the SoC is known to only
partially reset the logic. A mechanism is implemented in
rk3399_force_power_on_reset to use a GPIO connected to the PMIC's
over-temperature (OTP) reset pin, which fully resets all logic.
Hook the associated GPIO where the function expects it to enable this
reset mechanism and avoid any possible side-effect of partially-reset
units.
Without this patch, reading from the micro sd slot fails after a reset.
With this mechanism, U-Boot is able to boot from it reliably.
