[PATCH 0/8] arm: mach-snapdragon: Qualcomm clock driver cleanup

[Caleb Connolly]

This series begins making some headway towards cleaning up Qualcomm
platform support in u-boot. The following is a rough overview of the
changes:

* Move the Qualcomm clock drivers out of mach-snapdragon and into clk/qcom
* Introduce per-platform clock driver configs to decouple Qualcomm platform
  support from mach-snapdragon targets.
* Add the IPQ4019 clock driver, removing it from mach-ipq40xx and introducing
  the reset map.
* Merge the qcom reset driver is into clk/qcom and rework it to be
  compatible with upstream devicetrees.
* A callback model is added so that multiple clock drivers can be
  compiled in at once.
* SDM845 gains support for enabling/disabling all gate clocks (CBC's) by
  way of a new "gate_clk" abstraction.
* Preperatory cleanup work is done to simplify the bringup process for
  new platforms.

Further details are included in each commit.

The primary goal of this series is to prepare for enabling several new
Qualcomm platforms in u-boot as well as additional peripherals, while
minimising the amount of copy/pasted board-specific code.

This series conflicts with a previous series introducing support for the
Qualcomm RB2 board [1], I plan to resend this initial support pending
acceptance of this series and several other cleanups.
