In some cases it is necessary to read the keyboard in early phases of U-Boot. The cros_ec keyboard is kept in the misc directory. Update the config to allow this.

Leave the misc uclass alone since it stops sandbox_spl working

bool "Enable Driver Model for Misc drivers in SPL"depends on SPL_DMhelpEnable driver model for miscellaneous devices. This class isused only for those do not fit other more general classes. Aset of generic read, write and ioctl methods may be used toaccess the device.Platforms currently use CONFIG_SPL_DRIVERS_MISC_SUPPORT and CONFIG_MISC to enable the MISC drivers in the SPL.
This is a bit confusing but that is not my understanding of the situation.
CONFIG_MISC enables UCLASS_MISC devices. The 'misc' drivers directory is included always in U-Boot proper. Yes the CONFIG_SPL_DRIVERS_MISC_SUPPORT option is for SPL only.
But in my case I want an option to enable driver-model MISC devices in SPL/TPL. Oddly this is orthogonal to whether the drivers/misc directory itself is included in the build.
Ok. that makes sense now.
Applied to u-boot-dm.
