This adds a generic sim that abstract a lot of what needs to be implemented in a driver for mmccam support. A new interface with three methods is added : - mmc_sim_get_tran_settings: Use to get what the controller supports in term of capabilities, freq etc ... - mmc_sim_set_tran_settings: Use to change the speed/freq/etc of the sdcard host controller - mmc_sim_cam_request: Used for MMCIO requests Differential Revision: https://reviews.freebsd.org/D27485 Reviewed by: kibab
