[PATCH v13 7/7] spacemit: k1: fix product name detection and DTB matching in SPL

[Eric Chung <eric.chung@riscstar.com>]

Use a table to handle DTB matching.

Signed-off-by: Eric Chung <eric.chung@riscstar.com>

v7:
- Abandon to load product name from ENV.
v6:
- Rebased onto latest upstream. Cleaned up board_fit_config_name_match()
  to maintain consistentcy with v5.
