This default console mechanism is not used if the console is selected
by command line (console= parameter).
Dropping this will simplify the compilation of multiple SoC in the same
kernel image.

This variable spread on every SoC that is using the atmel_serial.c
driver can be included directly into the latter.

This will allow to compile multiple soc in the same kernel.

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.
