GPIO0 and GPIO1 are linked to unique interrupt line in PXA series,
others are linked to another interrupt line. All GPIO are linked to one
interrupt line in MMP series.

Since gpio driver is shared between PXA series and MMP series, define
GPIO0 and GPIO1 as chained interrupt chip. So we can move out gpio code
from irq.c to gpio-pxa.c.

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

3) demuxing the clk source
