bootstd: Add the bootdev uclass
A 'bootdev' is a device which can be used to boot an operating system. It is a child of the media device (e.g. MMC) which handles reading files from that device, such as a bootflow file. Add a uclass for bootdev and the various helpers needed to make it work. Also add a binding file, empty for now. Signed-off-by: Simon Glass <sjg@chromium.org>

+U-Boot boot device (bootdev)
+============================
+
+A bootdev provides a way to obtain a bootflow file from a device. It is a
+child of the media device (UCLASS_MMC, UCLASS_SPI_FLASH, etc.)
+
+The bootdev driver is provided by the media devices. The bindings for each
+are described in this file (to come).
