Introduce clock divider driver and bindings for AM62 DSS (VP0).
The OLDI transmitters in AM62 SoC, require a serial clock, which is 7
times the pixel clock required by the Video Port 0 (VP0) of the DSS.
The clock architecture is such that the relevant PLL is connected to the
DSS VP0 through a clock divider (by-7). The DSS requests the pixel clock
to the clock divider, which forwards the request to parent PLL. The PLL,
in turn, is supposed to generate a 7x pixel-clock (serial clock) to feed
the OLDI transmitters directly, and the DSS through the said divider.
This ensures that both the OLDI TXes and DSS get their required clocks.
Change Log:
v2:
- Create separate devicetree binding and driver for the clock.
The previous version of the series added the compatible inside the
fixed-factor clock driver, and explicitly set the flag
CLK_SET_RATE_PARENT to have the set clock rate request propagate to
the parent PLL. The driver is referenced from the fixed-factor clock
driver and modified specifically to support AM62 DSS requirements.

On TI's AM62 Family of SoCs, the pixel frequency of the DSS Video Port 0
comes from a by-7 clock divider. This is done to support the clock for
OLDI transmitters that need serial clock 7 times the pixel frequency.
A clock set request on this clock, is forwarded to its parent clock by
default, using the SET_RATE_PARENT flag. The PLL (in this case the
parent) generates serial clock for OLDI, which is then also fed to DSS
using this clock divider.
