instead of reading the registers everytime

the current implementation respect the following constrain:
 - allow 1 to n soc to be enabled
 - allow to have a virtual cpu type and subtype
 - always detect the cpu type and subtype and report it
 - detect if the soc support is enabled
 - prepare for sysfs export support
 - drop soc specific code via compiler when the soc not enabled
   (via cpu_is_xxx)

Today if we read the exid we will have the same value for 9g35 and 9m11
and we will need to check the cidr too

with the new implementation we just need to check the soc subtype

this will also allow to have specific virtual subtype for rm9200 which the
board will have to specify via at91rm9200_set_type(int) as we have no way to
detect it.

this implementation is inspired by the SH cpu detection support

Now most of ARM machines has the alsmot same __clk_get/put() macro

So place it at the arch/arm/include/asm/clkdev.h and remove the reduntant header files

But some machines don't have the same form as above. It can use the machince specific clkdev file by HAVE_MACH_CLKDEV config

Now there are only 3 caese.

1) define the clk structure with clkdev macro => Need to move clk structure to proper header file

arch/arm/mach-versatile/include/mach/clkdev.h
arch/arm/mach-realview/include/mach/clkdev.h
arch/arm/mach-vexpress/include/mach/clkdev.h
arch/arm/mach-integrator/include/mach/clkdev.h

2) export the __clk_get/put function at clock.c

arch/arm/mach-shmobile/include/mach/clkdev.h

3) demuxing the clk source

The recently modified nand buswitth configuration is not aligned with
board reality: the double footprint on boards is always populated with 8bits
buswidth nand flashes.
So we have to consider that without particular configuration the 8bits
buswidth is selected by default.
Moreover, the previous logic was always using !board_have_nand_8bit(), we
change it to a simpler: board_have_nand_16bit().

Hello,

I am not 100% sure this is the right thing to do, but it makes the
atmel-ssc driver happy on my at91rm9200 board.

This unifies the con_id across all at91 machines.

The atmel-ssc driver expects the con_id to be "pclk" or it will fail probing.

I no longer work at Bluewater Systems. Update my email address accordingly. I
have deleted my email address from C files rather than change it. This
was suggested by several people, since the commit from my new email
address will cause scripts/get_maintainer.pl to function properly. I
have not added the .mailmap entry as suggested by Joe because I think
it is no longer necessary if I touch all the files which had my name
