Subject: [PATCH v9 15/27] ARM: davinci: switch to common clock framework

This switches ARCH_DAVINCI to use the common clock framework. The legacy
clock code in arch/arm/mach-davinci/ is no longer used. New drivers in
drivers/clk/davinci/ are used instead.

A few macros had to be moved to prevent compilation errors.
