[U-Boot] [PATCH v2 10/10] bootstage: Allow SPL to obtain bootstage info from TPL

[sjg at google.com]

It is possible to enable bootstage in TPL. TPL can stash the info for SPL.
But at present this information is then lost because SPL does not read
from the stash.

Add support for SPL not being the first phase to enable bootstage.

Changes in v2:
- Adjust SPL logic to avoid failing if TPL does not provide bootstage data
- Add a new patch to support %p without DEBUG in tiny-printf
