[PATCH v2 05/30] u_boot_pylib: Improve ANSI-colour output with backgrounds

[Simon Glass]

The current implementation does not handle background colours very well:

- It outputs an incorrect code in some cases, leading to wrong colours
- Some functions lack a control for the background

Tidy this up so that background colours can be used in more places.
