This patch implements the new two cells binding for SCU clocks. The usage is as follows: clocks = <&uart0_clk IMX_SC_R_UART_0 IMX_SC_PM_CLK_PER> Due to each SCU clock is associated with a power domain, without power on the domain, the SCU clock can't work. So we create platform devices for each domain clock respectively and manually attach the required domain before register the clock devices, then we can register clocks in the clock platform driver accordingly. Note because we do not have power domain info in device tree and the SCU resource ID is the same for power domain and clock, so we use resource ID to find power domains. Later, we will also use this clock platform driver to support suspend/resume and runtime pm.

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.
