From: Alexandre Belloni <alexandre.belloni@free-electrons.com>

3.4.108-rc1 review patch. If anyone has any objections, please let me know.

------------------

commit 84e871660bebfddb9a62ebd6f19d02536e782f0a upstream.

at91rm9200 standby and suspend to ram has been broken since
00482a4078f4. It is wrongly using AT91_BASE_SYS which is a physical address
and actually doesn't correspond to any register on at91rm9200.

Use the correct at91_ramc_base[0] instead.

Fixes: 00482a4078f4 (ARM: at91: implement the standby function for pm/cpuidle)
