Change slow_clock()/at91_slow_clock() prototype to accept the PMC
base address and one or two RAM controller addresses by parameters.
The r0, r1 and r2 registers are used differently and preserved during
function call.
Those values are defined in pm.c and slow_clock() function is called
from there with its new parameters.
This will allow to have a soc independent pm_slowclock.

This patch groups the self-refresh on/cpu_do_idle/self-refresh off into
a single 'standby' function.
The standby routine for rm9200 has been turned into an asm routine to have
a better control of the self refresh and to prevent a memory access when
running this code.
Draining the write buffer is done automatically when switching for the self
refresh on sam9, so the instruction is added to the rm9200 only.

All the "wait_for_interrupt" definition are aliases to cpu_do_idle.
Only the rm9200 has an asm routine to switch to wfi. But the cpu_do_idle
for this platform has exactly the same asm routine.
arch/arm/mm/proc-arm920.S
..
ENTRY(cpu_arm920_do_idle)
mcr p15, 0, r0, c7, c0, 4 @ Wait for interrupt
..
Then it is safe to invoke cpu_do_idle for this platform. As all the
wait_for_interrupts are definition for cpu_do_idle, let's remove it
and replace its invokation by cpu_do_idle.

a092f2b153: "ARM: 7291/1: cache: assume 64-byte L1 cachelines for

Since commit 576d2f2525 "ARM: add
generic ioremap optimization by reusing static mappings" ioremap()
is trying to reuse existing static mapping when possible.
The condition checking boundaries of the requested and existing
mappings didn't take in-page offset into consideration though,
which lead to obscure and hard to debug problems when requested
mapping crossed end of the static one.
