Subject: [PATCH] dm: core: Add Kconfig for simple bus driver
Add Kconfig entries for the simple-bus driver, both for U-Boot
and for SPL. The simple-bus is enabled by default in U-Boot and
disabled by default in SPL to preserve the original behavior.

Modified to fit on top of Masahiro's $(SPL) setup:
