msm: acpuclock-8930: Move 8930 support to use acpuclock-krait
The acpuclock-krait library is an evolution of acpuclock-8960 with
several improvements. By dropping support for older versions of the
Krait processors and taking advantages of features only available on
newer Kraits, acpuclock-krait is both simpler and more efficient than
its predecessor. Key advantages in moving Krait targets to the newer
driver include:
- The ability to write to one CPU's CP15 registers from another CPU.
This means it's possible to change a CPU's clock sources after
power-collapsing it, rather than needing to select a low-power
source while it's still up (which slowed down the hotplug path).
It also means acpuclk_set_rate() can be called from any CPU.
- Dropping of obsolete Krait v1 processor errata workarounds.
- Relocation of SoC-specific data into its own files
- Shorter, more readable code
