So far we have a sunxi_private.h header file in the common code directory.
This holds the prototypes of various functions we share in *common*
code. However we will need some of those in the platform specific code
parts as well, and want to introduce new functions shared across the
whole platform port.
So move the sunxi_private.h file into the common/include directory, so
that it becomes visible to all parts of the platform code.
Fix up the existing #includes and add missing ones, also add the
sunxi_read_soc_id() prototype here.
This will be used in follow up patches.

The "INFO" output in sunxi_cpu_ops.c is quite verbose, so make this more
obvious by changing the log level to "VERBOSE" and so avoiding it to
be printed in a normal (even debug) build.

sun50i_cpu_on will be used by the PSCI implementation to initialize
secondary cores for SMP. Unfortunately, sun50i_cpu_off is not usable by
PSCI directly, because it is not possible for a CPU to use this function
to power itself down. Power cannot be shut off until the outputs are
clamped, and MMIO does not work once the outputs are clamped.
But at least CPU0 can shutdown the other cores early in the BL31 boot
process and before shutting down the system.
