The RZ/G1M (r8a7743) uses the R-Car Gen2 core, but not the R-Car Gen2 clock
driver. This is a harbinger of a transition for R-Car Gen2 SoCs. As the
process to get all the required pieces in place is somewhat complex it
seems useful to try to disentangle dependencies where possible.
The approach here is to temporarily disable calling rcar_gen2_clocks_init()
if no R-Car Gen2 SoC are configured and thus the symbol will not be
present.

This fixes pwm name matching for DA850 familiy devices. When using device
tree, the da850_auxdata_lookup[] table caused pwm devices to have the exact
same name, which caused errors when trying to register the devices.
We cannot have multiple entries for the same clock in in da850_clks[], so
we have added child clocks to the EHRPWM and ECAP LPSC clocks so that each
PWM device will have its own clock for proper name matching.

The usb20_phy clock needs to be registered for the driver to be able
to get and enable a clock. Currently the usb phy clocks are registered
from board files, which will not be called during a device tree based
boot.
To be able to probe correctly usb form a device tree boot, register
the usb phy clocks from the DT specific init.
Unfortunately, davinci does not have proper clock support on device tree
yet, so by registering the clock from the DT specific file we are
forced to hardcode the parent clock, and cannot select refclkin as
parent for any of the phy clocks of the da850 family.
As none of the current da850 based boards currently in mainline use
refclkin as source. I guess we can live with this limitation until clocks
are correctly represented through CCF/device tree.

Up to this point, the USB phy clock configuration was handled manually in
the board files and in the usb drivers. This adds proper clocks so that
the usb drivers can use clk_get and clk_enable and not have to worry about
the details. Also, the related code is removed from the board files and
replaced with the new clock registration functions.
This also removes the #if IS_ENABLED(CONFIG_USB_MUSB_HDRC) around the musb
declaration and renames the musb platform device so that we can reference
it from the usb20 clock even if the musb device is not used.

for the omap138-lcdk board, this would prevent the usb11 phy to probe

By calling regulator_has_full_constraints(), An error would be returned
instead of -EPROBE_DEFER for the regulator, and the probe of the phy driver
can continue normally without a regulator.
