commonlib: Move drivers/storage into commonlib/storage

Move drivers/storage into commonlib/storage to enable access by
libpayload and indirectly by payloads.

* Remove SD/MMC specific include files from include/device
* Remove files from drivers/storage
* Add SD/MMC specific include files to commonlib/include
* Add files to commonlib/storage
* Fix header file references
* Add subdir entry in commonlib/Makefile.inc to build the SD/MMC driver
* Add Kconfig source for commonlib/storage
* Rename *DEVICE* to *COMMONLIB*
* Rename *DRIVERS_STORAGE* to *COMMONLIB_STORAGE*

TEST=Build and run on Galileo Gen2
