Max Filippov b06c14e5c1 xtensa: provide default platform_pcibios_init implementation
This fixes the following build error:

  arch/xtensa/kernel/built-in.o:(.init.literal+0xe8): undefined reference
	to `platform_pcibios_init'
  arch/xtensa/kernel/built-in.o: In function `setup_arch':
  (.init.text+0x20e): undefined reference to `platform_pcibios_init'

and allows platform to omit definition of platform_pcibios_init if it's
empty.

Johannes Weiner 4476c96769 xtensa: remove platform rtc hooks
platform_get/set_rtc_time() is not implemented by any of the supported
xtensa platforms.  Remove the facility completely.

The initial seconds for xtime come from read_persistent_clock() which
returns just 0 in the generic implementation.  Platforms that sport a
persistent clock can implement this function.

This is needed to implement the ccount as a clock source.

Tim Schmielau 4e57b68178 [PATCH] fix missing includes
I recently picked up my older work to remove unnecessary #includes of
sched.h, starting from a patch by Dave Jones to not include sched.h
from module.h. This reduces the number of indirect includes of sched.h
by ~300. Another ~400 pointless direct includes can be removed after
this disentangling (patch to follow later).
However, quite a few indirect includes need to be fixed up for this.

In order to feed the patches through -mm with as little disturbance as
possible, I've split out the fixes I accumulated up to now (complete for
i386 and x86_64, more archs to follow later) and post them before the real
patch.  This way this large part of the patch is kept simple with only
adding #includes, and all hunks are independent of each other.  So if any
hunk rejects or gets in the way of other patches, just drop it.  My scripts
will pick it up again in the next round.
