clk/qcom: handle resets and clocks in one device

Qualcomm's clock controller blocks actually do much more than it
says on the tin.. They provide clocks, resets and power domains.
Currently, U-Boot requires one to spawn 2 separate devices for
controlling clocks and resets, both spanning the same register space.
Refactor the code to make it work with just a single DT node, making
it compatible with upstream Linux bindings and dropping the dedicated
reset driver in favour of including it in the clock driver.

Heavily inspired by Renesas code for a similar hw block.

[caleb: moved drivers to clk/qcom, added reset driver and adjusted bind
logic. Imported qcom,gcc-ipq4019.h from Linux]
