Furquan Shaikh b038f41420 vboot: Add support for recovery hash space in TPM
1. Add a new index for recovery hash space in TPM - 0x100b
2. Add helper functions to read/write/lock recovery hash space in TPM
3. Add Kconfig option that can be selected by mainboards that want to
define this space.
4. Lock this new space while jumping from RO to RW.

BUG=chrome-os-partner:59355
BRANCH=None
TEST=Verified use of recovery hash space on reef.
