The Global Clock Controller (GCC) in the MSM8909 SoC provides clocks,
resets and power domains for the various hardware blocks in the SoC.
Add a driver for it to make it possible to enable additional
functionality for the SoC.
Work on this driver was originally started independently by Dominik,
I picked it up and added missing clocks/resets, as well as various
cleanup to bring it into shape for mainline.

On recent Qualcomm platforms the QMP PIPE clocks feed into a set of
muxes which must be parked to the "safe" source (bi_tcxo) when
corresponding GDSC is turned off and on again. Currently this is
handcoded in the PCIe driver by reparenting the gcc_pipe_N_clk_src
clock. However the same code sequence should be applied in the
pcie-qcom endpoint, USB3 and UFS drivers.
Rather than copying this sequence over and over again, follow the
example of clk_rcg2_shared_ops and implement this parking in the
enable() and disable() clock operations. Supplement the regmap-mux with
the new clk_regmap_phy_mux type, which implements such multiplexers
as a simple gate clocks.
This is possible since each of these multiplexers has just two clock
sources: one coming from the PHY and a reference (XO) one. If the clock
is running off the from-PHY source, report it as enabled. Report it as
disabled otherwise (if it uses reference source).
This way the PHY will disable the pipe clock before turning off the
GDSC, which in turn would lead to disabling corresponding pipe_clk_src
(and thus it being parked to a safe, reference clock source). And vice
versa, after enabling the GDSC the PHY will enable the pipe clock, which
would cause pipe_clk_src to be switched from a safe source to the
working one.
