[PATCH v5 30/44] ARM: da8xx: add new sata_refclk init using common clock frmework

[David Lechner]

This adds the new SATA REFCLK clock init in mach-davinci/devices-da8xx.c
using the new common clock framework drivers.

The #ifdefs are needed to prevent compile errors until the entire
ARCH_DAVINCI is converted.

Also, the #includes are sorted since we are adding some here.

[PATCH v5 31/44] ARM: davinci: remove CONFIG_DAVINCI_RESET_CLOCKS

[David Lechner]

The common clock framework will take care of disabling unused clocks when
we switch from the legacy davinci clocks and having this enabled will
cause compile errors after we switch, so remove it now.

[PATCH v5 33/44] ARM: davinci: switch to common clock framework

[David Lechner]

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 compile errors.
