[PATCH v3 10/22] bootm: Add more fields to bootm_info

[Simon Glass]

Add fields for the three bootm parameters and other things needed for
booting. Also add a helper to set up the struct correctly.

Signed-off-by: Simon Glass <sjg at chromium.org>

Changes in v3:
- Rename addr_fit to addr_img in struct bootm_info

Changes in v2:
- Split out adding the rest of struct bootm_info fields to separate patch
