This commit does the following to clean up x86 cpu dm drivers: - Move cpu_x86 driver codes from arch/x86/cpu/cpu.c to a dedicated file arch/x86/cpu/cpu_x86.c - Rename x86_cpu_get_desc() to cpu_x86_get_desc() to keep consistent naming with other dm drivers - Add a new cpu_x86_bind() in the cpu_x86 driver which does exactly the same as the one in the intel baytrail cpu driver - Update intel baytrail cpu driver to use cpu_x86_get_desc() and cpu_x86_bind() Signed-off-by: Bin Meng <bmeng.cn@gmail.com> Acked-by: Simon Glass <sjg@chromium.org>
