From: Tom Rini trini@konsulko.com
A valid memory location to stash bootstage information at will be architecture dependent. Move the existing defaults to the main Kconfig file for this option and set 0x0 as the default only for sandbox.

Changes in v3: - Use stub functions to avoid unnecessary #ifdefs
Changes in v2: - Seeing that BOOTSTAGE_STASH_ADDR did not depend on BOOTSTAGE_STASH in turn lead to discovering that (minor) BOOTSTAGE_STASH_SIZE was also missing a depends on line and then that a number of places built code with BOOTSTAGE_STASH_ADDR=0x0 as a compiles-but-likely-fails option. Rework a number of spots to guard usage around BOOTSTAGE_STASH being enabled.
