This makes the assumption that setting up pinctrl in cpu_init_r() is safe.
On samus we need GPIOs before relocation in order to support power control.
This commit fixes the following message on boot:

   initcall sequence ffe5c6f4 failed at call ffe01d3d (err=-1)
   ### ERROR ### Please RESET the board ###

In any case it seems better to leave init to driver model, so that it can
pick up the GPIO driver when it needs it. Since pinctrl is a dependency of
the GPIO driver, we may as well put the dependency there and avoid these
problems.

Our build system still parses ad-hoc CONFIG options in header files
and generates include/autoconf.mk so that Makefiles can reference
them.  This gimmick was introduced in the pre-Kconfig days and will
be kept until Kconfig migration is completed.

The include/autoconf.mk is generated like follows:

  [1] Preprocess include/common.h with -DDO_DEPS_ONLY and
      retrieve macros into include/autoconf.mk.tmp
  [2] Reformat include/autoconf.mk.dep into include/autoconf.mk
      with tools/scripts/define2mk.sed script
  [3] Remove include/autoconf.mk.tmp

Here, include/autoconf.mk.tmp is similar to u-boot.cfg, which is
also generated by preprocessing include/config.h with -DDO_DEPS_ONLY.
In other words, there is much overlap among include/autoconf.mk and
u-boot.cfg build rules.

So, the idea is to split the build rule of include/autoconf.mk
into two stages.  The first preprocesses headers into u-boot.cfg.
The second parses the u-boot.cfg into include/autoconf.mk.  The
build rules of u-boot.cfg in Makefile and spl/Makefile will be gone.

If somebody adds references to new CONFIG options in source files,

new options CONFIG_SPL_DFU_SUPPORT and CONFIG_USB_XHCI_UNIPHIER will
appear in the list.)

In order to make steady progress of Kconfig migration, we want to
only decrease whitelist options, but never increase.

So, when we update the whitelist, we should create a temporary list,
then take the intersection of the temporary one and the current one.
