When adding in the indexes for this clock-controller we missed
GCC_CAMSS_CSI2_AHB_CLK, GCC_CAMSS_CSI2_CLK, GCC_CAMSS_CSI2PHY_CLK,
GCC_CAMSS_CSI2PIX_CLK and GCC_CAMSS_CSI2RDI_CLK.
Add them in now and rename ftbl_gcc_camss_csi0_1_clk
to account for csi2 also using it.

The DT of_device.h and of_platform.h date back to the separate
of_platform_bus_type before it as merged into the regular platform bus.
As part of that merge prepping Arm DT support 13 years ago, they
"temporarily" include each other. They also include platform_device.h
and of.h. As a result, there's a pretty much random mix of those include
files used throughout the tree. In order to detangle these headers and
replace the implicit includes with struct declarations, users need to
explicitly include the correct includes.

Change several entries of parent_data to use parent_hws instead, which

Similar to msm8916, msm8939 has (at least) 6 "General Purpose" clocks that
can be muxed to SoC pins. These clocks are:
GP_CLK{0, 1} : GPIO_{31, 32} (Belongs to CAMSS according to Linux)
GP_CLK_{1-3}{A, B} : GPIO_{49-51, 97, 12, 13} (Belongs to GCC itself)
GP_MN : GPIO_110 (Doesn't seem to be described in gcc,
ignored in this patch)
Those clocks may be used as e.g. PWM sources for external peripherals.
Add more frequencies to the table for those clocks so it's possible
for arbitrary peripherals to make use of them.

Reviewing the qcom msm8936.c clock frequency tables we see
static struct clk_freq_tbl ftbl_gcc_camss_cpp_clk[] = {

The Venus clock frequencies are a copy/paste error from msm8916. Looking
at the original clock-gcc-8936.c ftbl_gcc_venus0_vcodec0_clk defines we
have:
- 133 MHz
- 200 MHz
- 266 MHz
These values are born out by the relevant qualcomm documentation for the
msm8936/msm8939 Venus core performance levels.

The msm8939 has an additional higher operating point for the multi-media
peripherals. The higher throughput MM componets operate off of the
system-mm noc not the system noc.
system_mm_noc_bfdcd_clk_src is the source clock for the higher frequency
capable system noc mm.
Maximum frequency for the MM SNOC is 400 MHz.

This patch adds support for the MSM8939 GCC. The MSM8939 is based on the
MSM8916. MSM8939 is compatible in several ways with MSM8916 but, has
additional functional blocks added which require additional PLL sources. In
some cases functional blocks from the MSM8916 have different clock sources
or different supported frequencies.
