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
arch/arm/mach-u300/include/mach/clkdev.h

Convert PCIBIOS_MIN_IO and PCIBIOS_MIN_MEM to variables to allow
multi-platform builds. This also removes the requirement for a platform to
have a mach/hardware.h.
The default values for i/o and mem are 0x1000 and 0x01000000, respectively.
Per Arnd Bergmann, other values are likely to be incorrect, but this commit
does not try to address that issue.

Currently, both the WM8903 and TPS6586x chips attempt to register with
gpiolib using the same GPIO numbers. This causes the audio driver to
fail to initialize.
To solve this, add a define to board-harmony.h for the TPS6586x, and make
board-harmony-power.c use this define, instead of directly referencing
TEGRA_NR_GPIOS.
This fixes a regression introduced by commit
6f168f2fa6.

This patch allows the mach-tegra support to tell the tegra MMC host
controller to NOT turn off power for the MMC controller the WIFI part
lives behind. Thus bcm4329 firmware doesn't need to be reloaded.

regulator on the PMIC and another one is controlled by a PMIC GPIO.
