[U-Boot] [PATCH v4 3/8] main: Remove CONFIG #ifdefs from the abortboot() code

[Simon Glass]

Move this code over to using autoconf. We can add the autoconf values to
the delaykey[] array, and move the code that checks for autoconf values into
the loop.

Also change to using ARRAY_SIZE on delaykey[].
