I ran into a build error on ARM with a platform that has a non-standard
clk implementation:

drivers/clk/clk.o: In function `clk_disable':
clk.c:(.text.clk_disable+0x0): multiple definition of `clk_disable'
arch/arm/mach-omap1/clock.o:clock.c:(.text.clk_disable+0x0): first defined here
drivers/clk/clk.o: In function `clk_enable':
clk.c:(.text.clk_enable+0x0): multiple definition of `clk_enable'
arch/arm/mach-omap1/clock.o:clock.c:(.text.clk_enable+0x0): first defined here

The problem is a device driver that uses 'select COMMON_CLK', which is
generally a bad idea: selecting a subsystem should only be done from
a platform, otherwise we run into circular dependencies. The same driver
also selects 'GPIOLIB' and 'I2C', which has a similar effect.

This turns all three into 'depends on', as it should be.

Finally, we can limit the build to x86, unless we are compile testing.

Fixes: 2f91ded5f8f4 ("mfd: Add Cherry Trail Whiskey Cove PMIC driver")

Applied, thanks.
