Ilya Bakulin 02c474b481 Miscellaneous fixes and improvements to MMCCAM stack
* Demote the level of several debug messages to CAM_DEBUG_TRACE
 * Add detection for SDHC cards that can do 1.8V. No voltage switch sequence
   is issued yet;
 * Don't create a separate LUN for each SDIO function. We need just one to make
   pass(4) attach;
 * Remove obsolete mmc_sdio* files. SDIO functionality will be moved into the
   separate device that will manage a new sdio(4) bus;
 * Terminate probing if got no reply to CMD0;
 * Make bcm2835 SDHCI host controller driver compile with 'option MMCCAM'.
