Stephen Warren 135aa95002 clk: convert API to match reset/mailbox style
The following changes are made to the clock API:
* The concept of "clocks" and "peripheral clocks" are unified; each clock
  provider now implements a single set of clocks. This provides a simpler
  conceptual interface to clients, and better aligns with device tree
  clock bindings.
* Clocks are now identified with a single "struct clk", rather than
  requiring clients to store the clock provider device and clock identity
  values separately. For simple clock consumers, this isolates clients
  from internal details of the clock API.
* clk.h is split so it only contains the client/consumer API, whereas
  clk-uclass.h contains the provider API. This aligns with the recently
  added reset and mailbox APIs.
* clk_ops .of_xlate(), .request(), and .free() are added so providers
  can customize these operations if needed. This also aligns with the
  recently added reset and mailbox APIs.
* clk_disable() is added.
* All users of the current clock APIs are updated.
* Sandbox clock tests are updated to exercise clock lookup via DT, and
  clock enable/disable.
* rkclk_get_clk() is removed and replaced with standard APIs.

Buildman shows no clock-related errors for any board for which buildman
can download a toolchain.

test/py passes for sandbox (which invokes the dm clk test amongst
others).

PIC32MZ[DA] Starter Kit
----------------------------------------
PIC32MZ[DA] Starter Kit is based on PIC32MZ[DA] family of micro-controller.
This family is powered by MIPS M14KEC 32bit general purpose core and has
advanced microcontroller features and peripherals.

This processor boots with proprietary stage1 bootloader running from internal
boot-flash. Stage1 bootloader inturns locates and jumps to U-Boot programmed
on internal program-flash. Finally U-Boot loads OS image (along with other
required files for booting) from either uSD card, or ethernet, or from USB
storage.

To boot Linux following three files are mandatory - uEnv.txt (custom U-Boot
environment file), uImage, *.dtb (platform device-tree-blob file).

U-Boot jumps to Linux using UHI specification.
