preboot: Introduce CONFIG_USE_PREBOOT and migrate CONFIG_PREBOOT
This is the same migration path as commit b6251db8c3f0 ("Kconfig:
Introduce USE_BOOTCOMMAND and migrate BOOTCOMMAND").
I also moved the description in README to the Kconfig help.
I ripped off the sentence about 'LWMON' since it is gone already.
I only let my boards migrate, leaving the rest to platform maintainers.
