The cpu_do_idle() function is always used by the cpuidle drivers.
That led to have each driver including cpuidle.h and proc-fns.h, they are
always paired. That makes a lot of duplicate headers inclusion. Instead of
including both in each .c file, move the proc-fns.h header inclusion in the
cpuidle.h header file directly, so we can save some line of code.

As the result of commit b82b6cca48 ("cpuidle: Invert
CPUIDLE_FLAG_TIME_VALID logic"), the flag gets removed and hence we see
the compile error below.
CC arch/arm/mach-imx/cpuidle-imx6sx.o
arch/arm/mach-imx/cpuidle-imx6sx.c:69:13: error: ‘CPUIDLE_FLAG_TIME_VALID’ undeclared here (not in a function)
Since the behavior of the original flag has been the default, we can
simply drop the flag now.

This patch introduces an independent cpuidle driver for
i.MX6SX, and supports arm power off in idle, totally
3 levels of cpuidle are supported as below:
1. ARM WFI;
2. SOC in WAIT mode;
3. SOC in WAIT mode + ARM power off.
ARM power off can save at least 5mW power.
This patch also replaces imx6q_enable_rbc with imx6_enable_rbc.
