[PATCH 21/24] kconfig: prefix hex values with 0x in .config

[Sam Ravnborg <sam@ravnborg.org>]

We could hit a situation where hex values
are stored internally in kconfig without 0x prefix, so if we see
one of these add 0x prefix when we write value to .config.
The real fix is to make sure we always prefix hex
values with 0x in kconfig.
