The bulk of the changes are updates and fixes to existing clk provider

drivers, along with a pretty standard number of new drivers. The core
 recieved a small number of updates as well.
 
 Core changes of note:
 * Removed CLK_IS_ROOT flag
 
 New clk provider drivers:
 * Renesas r8a7796 Clock Pulse Generator / Module Standby and Software
   Reset
 * Allwinner sun8i H3 Clock Controller Unit
 * AmLogic meson8b clock controller (rewritten)
 * AmLogic gxbb clock controller
 * Support for some new ICs was added by simple changes to static data
   tables for chips sharing the same family
 
 Driver updates of note:
 * the Allwinner sunxi clock driver infrastucture was rewritten to
   comform to the state of the art at drivers/clk/sunxi-ng. The old
   implementation is still supported for backwards compatibility with the
   DT ABI

* Amlogic GXBB Clock and Reset Unit
The Amlogic GXBB clock controller generates and supplies clock to various
controllers within the SoC.
Required Properties:
- compatible: should be "amlogic,gxbb-clkc"
- reg: physical base address of the clock controller and length of memory
mapped region.
- #clock-cells: should be 1.
Each clock is assigned an identifier and client nodes can use this identifier
to specify the clock which they consume. All available clocks are defined as
preprocessor macros in the dt-bindings/clock/gxbb-clkc.h header and can be
used in device tree sources.
Example: Clock controller node:
clkc: clock-controller@c883c000 {
#clock-cells = <1>;
compatible = "amlogic,gxbb-clkc";
reg = <0x0 0xc883c000 0x0 0x3db>;
};
Example: UART controller node that consumes the clock generated by the clock
controller:
uart_AO: serial@c81004c0 {
compatible = "amlogic,meson-uart";
reg = <0xc81004c0 0x14>;
interrupts = <0 90 1>;
clocks = <&clkc CLKID_CLK81>;
status = "disabled";
};

Allwinner Clock Control Unit Binding
------------------------------------
Required properties :
- compatible: must contain one of the following compatible:
- "allwinner,sun8i-h3-ccu"
- reg: Must contain the registers base address and length
- clocks: phandle to the oscillators feeding the CCU. Two are needed:
- "hosc": the high frequency oscillator (usually at 24MHz)
- "losc": the low frequency oscillator (usually at 32kHz)
- clock-names: Must contain the clock names described just above
- #clock-cells : must contain 1
- #reset-cells : must contain 1
Example:
ccu: clock@01c20000 {
compatible = "allwinner,sun8i-h3-ccu";
reg = <0x01c20000 0x400>;
clocks = <&osc24M>, <&osc32k>;
clock-names = "hosc", "losc";
#clock-cells = <1>;
#reset-cells = <1>;
