[U-Boot] [PATCH 1/4 v2] config_defaults.h: new header for common u-boot config defaults

[Mike Frysinger]

There are a bunch of features in U-Boot that we want to enable by default,
and it's best if we centralize them in one place rather than updating all
the board files out there.

note: the LMB patch should be applied before this small series to avoid
conflicts -- there isnt any actual dependency on each other
