avb2.0: add proper dependencies
1. Since libavb library alone is highly portable, introduce dedicated
Kconfig symbol for AVB bootloader-dependent operations, so it's possible
to build libavb separately. AVB bootloader-dependent operations include:
* Helpers to process strings in order to build OS bootargs.
* Helpers to access MMC, similar to drivers/fastboot/fb_mmc.c.
* Helpers to alloc/init/free avb ops.
2. Add CONFIG_FASTBOOT dependency, as fastboot buffer is
re-used in partition verification operations.
