[ Upstream commit 1a500e0bc97b6cb3c0d9859e81973b8dd07d1b7b ]
On SM8350 platform the PCIe PIPE clocks require additional handling to
function correctly. They are to be switched to the tcxo source before
turning PCIe GDSCs off and should be switched to PHY PIPE source once
they are working. Switch PCIe PHY clocks to use clk_regmap_phy_mux_ops,
which provide support for this dance.

Per Stephen, clk providers need to include clk-provider.h, so include in
this driver as well

Use ARRAY_SIZE() instead of manually specifying num_parents. This makes
adding/removing entries to/from parent_data easy and errorproof.

Switch to using parent_hws instead of parent_data when parents are
defined in this driver and so accessible using clk_hw.
