Enable CPU opp tables for Orange Pi 3. This needs to change the CPU regulator max voltage to fit the OPP table. Also add the ramp-delay information to avoid any out of spec running as the regulator is slower at reaching the voltage requested compare to the PLL reaching the frequency. There is no such information for AXP805 but similar PMIC (AXP813) has a DVM (Dynamic Voltage scaling Management) ramp rate equal to 2500uV/us.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
