This patch adds cns3xxx_pwr_clk_dis, and exports these power management
functions that may be used by many other device drivers on CNS3XXX.

commit 6eb5d146d4 ("ARM: cns3xxx: Use IO memory accessors everywhere")
breaks cns3xxx_pwr_soft_rst_force() function, so that it doesn't write
cleared bit into the register.
This patch fixes the issue by adding the necessary __raw_writel().

Since we're now using addruart to establish the debug mapping, we can
remove the io_pg_offst and phys_io members of struct machine_desc.
The various declarations were removed using the following script:
grep -rl MACHINE_START arch/arm | xargs \
sed -i '/MACHINE_START/,/MACHINE_END/ { /\.\(phys_io\|io_pg_offst\)/d }'
[ Initial patch was from Jeremy Kerr, example script from Russell King ]

Rather than checking the MMU status in every instance of addruart, do it
once in kernel/debug.S, and change the existing addruart macros to
return both physical and virtual addresses. The main debug code can then
select the appropriate address to use.
This will also allow us to retreive the address of a uart for the MMU
state that we're not current in.

This patch adds PCIe support for CNS3xxx-based boards. The support
was tested with a directly attached SKY2 NIC, and EHCI USB controller
behind the PLX PEX8112 P2P bridge (to make sure that type1 cfg cycles
work as expected).

Before it isn't too late let's switch to IO memory accessors.
This patch converts all current _REG users and _REG definitions.
There should be no functional changes.

This patch adds very basic support for ECONA CNS3xxx ARM11 MPcore
(ARMv6) dual-core processors.
Note that SMP is not yet supported, as well as many peripheral
devices. Support for these features will be added later.
