[regression, bisected] rk3399-gru-kevin does not boot with 5.10-rc1

[Vicente Bergas]

Hi,
commit dd92f7dfe1ba3bad556c8a529edacce7c6fd0195
platform/chrome: Kconfig: Remove the transitional MFD_CROS_EC config
broke booting rk3399-gru-kevin.

The display does not turn on and there are no easy means to access the
serial port, so, no more information is available.

Regards,
  Vicente.
