drivers: move the early platform device support to arch/sh
SuperH is the only user of the current implementation of early platform
device support. We want to introduce a more robust approach to early
probing. As the first step - move all the current early platform code
to arch/sh.
In order not to export internal drivers/base functions to arch code for
this temporary solution - copy the two needed routines for driver
matching from drivers/base/platform.c to arch/sh/drivers/platform_early.c.
Also: call early_platform_cleanup() from subsys_initcall() so that it's
called after all early devices are probed.
