for_each_possible_cpu() is currently used to initialize cpufreq.
However, in cpu_dev_register_generic(), for_each_present_cpu()
is used to register CPU devices which means the CPU devices are
only registered for present CPUs and not all possible CPUs.
With nosmp or maxcpus=0, only the boot CPU is present, lead
to the cpufreq probe failure or defer probe due to no cpu device
available for not present CPUs.
Change for_each_possible_cpu() to for_each_present_cpu() in the
above cpufreq drivers to ensure it only registers cpufreq for
CPUs that are actually present.
Fixes: b0c69e1214bc ("drivers: base: Use present CPUs in GENERIC_CPU_DEVICES")

dev_pm_opp_cpumask_remove_table() is going to change in the next commit
and will not remove dynamic OPPs automatically. They must be removed
with a call to dev_pm_opp_remove().

Since the introduction of this driver, the functions to remove the opp
were added. So stop claiming we can't remove opp and use one of them in
case of failure.

In case of error the clock reference was freed but not in normal path
once it was nor more used. This patch fixes it.

Fix the use of 0 instead of NULL to clk_get() call. This stops the
following warning:
drivers/cpufreq/mvebu-cpufreq.c:73:40: warning: Using plain integer as NULL pointer

Move cpufreq bits for mvebu into drivers/cpufreq/ directory, that's
where they really belong to.
Compiled tested only.
