[U-Boot] [PATCH v3 09/16] main: Use autoconf for boot_delay code

[Simon Glass]

Convert this function and its children to use autoconf instead of #ifdef.

Some header files must now be included unconditionally, so remove some of
the #ifdefs from the header section, and put these header files into the
right order.

Changes in v3:
- Simplify code for finding out bootdelay from config or environment

Changes in v2: None
