This reverts commit 7cea0065.

The sa1100 cleanups fatally broke the SA1100 RTC driver - the first
hint that something is wrong are these compiler warnings:

drivers/rtc/rtc-sa1100.c:42:1: warning: "RCNR" redefined
In file included from arch/arm/mach-sa1100/include/mach/hardware.h:73,

and the second problem, which is far more severe, are the different
register layouts, resulting in the wrong registers being read on
SA11x0 platforms.  This patch adds:

	#define RCNR           0x00    /* RTC Count Register */
	#define RTAR           0x04    /* RTC Alarm Register */
	#define RTSR           0x08    /* RTC Status Register */
	#define RTTR           0x0c    /* RTC Timer Trim Register */

but the SA11x0 registers are:

	#define RTAR            __REG(0x90010000)  /* RTC Alarm Reg. */
	#define RCNR            __REG(0x90010004)  /* RTC CouNt Reg. */
	#define RTTR            __REG(0x90010008)  /* RTC Trim Reg. */
	#define RTSR            __REG(0x90010010)  /* RTC Status Reg. */

This reverts commit 7557c175.

This revert is necessary to revert the broken "RTC: sa1100:
support sa1100, pxa and mmp soc families" change.

Remove the now empty arch_reset() from all the mach/system.h includes,
and remove its callsite.  Remove arm_machine_restart() as this function
no longer does anything useful.

For samsung platforms, remove the include of mach/system-reset.h and
plat/system-reset.h from their respective mach/system.h headers as these
just define their arch_reset functions.  As a result, the s3c2410 and
plat-samsung system-reset.h files are no longer referenced, so remove
these files entirely.

sched_clock() is yet another blocker on the road to the single
image. This patch implements an idea by Russell King:

http://www.spinics.net/lists/linux-omap/msg49561.html

Instead of asking the platform to implement both sched_clock()
itself and the rollover callback, simply register a read()
function, and let the ARM code care about sched_clock() itself,
the conversion to ns and the rollover. sched_clock() uses
this read() function as an indirection to the platform code.
If the platform doesn't provide a read(), the code falls back
to the jiffy counter (just like the default sched_clock).

This allow some simplifications and possibly some footprint gain
when multiple platforms are compiled in. Among the drawbacks,
the removal of the *_fixed_sched_clock optimization which could
negatively impact some platforms (sa1100, tegra, versatile
and omap).

Tested on 11MPCore, OMAP4 and Tegra.

The poodle restart handler was added in 74617fb6 (3593/1: Add reboot
and shutdown handlers for Zaurus handhelds), and at that time it was
necessary to deal with the RCSR register.  This commit also forced all
restarts to use the 'hard' restart method.

In dc38e2ad (pxa: Fix RCSR handling), the RCSR handling was removed,
leaving just the forcing to use a 'hard' restart.  As hard restarts are
the default (in the absense of a reboot= command line argument), this
seems pointless.  In any case, Richard Purdie says:

> From what I remember that hardware either always reboots or always
> halts. I think the option was therefore left hardcoded to make it clear
> it wasn't expected to work. Later Zaurii models could do either but
> required some manual poking of registers to make it happen iirc.
>
> Regardless, you can probably clean this up as you suggest now.

So, lets remove the unnecessary interception and rely on the default
restart mode.

We only need to set the system up for a soft-restart if we're going to
be doing a soft-restart.  Provide a new function (soft_restart()) which
does the setup and final call for this, and make platforms use it.
Eliminate the call to setup_restart() from the default handler.

This means that platforms arch_reset() function is no longer called with
the page tables prepared for a soft-restart, and caches will still be
enabled.

Even when CONFIG_MULTI_IRQ_HANDLER is selected, the core code
requires the arch_irq_handler_default macro to be defined as
a fallback.

It turns out nobody is using that particular feature as both PXA
and shmobile have all their machine descriptors populated with
the interrupt handler, leaving unused code (or empty macros) in
their entry-macro.S file just to be able to compile entry-armv.S.

Make CONFIG_MULTI_IRQ_HANDLER exclusive wrt arch_irq_handler_default,
which allows to remove one test from the hot path. Also cleanup both
PXA and shmobile entry-macro.S.
