ARM: dts: sti: Add fixed clock for ehci and ohci nodes in stih410-b2260.dtsi
On STi platforms, all clocks are enabled by BOOTROM, so CONFIG_CLK is
not set as no clock driver for STI exists.
As ehci-generic and ohci-generic drivers are used on platforms where
CONFIG_CLK is set, clk_get_bulk() returns-ENOSYS in case of
stih410-b2260.
To avoid this error, add fixed clocks for ehci and ohci nodes for
stih410-b2260 to fix the following errors:
Bus usb@9a03c00: ohci_generic usb@9a03c00: Failed to get clocks (ret=-19)
Port not available.
Bus usb@9a03e00: ehci_generic usb@9a03e00: Failed to get clocks (ret=-19)
Port not available.
Bus usb@9a83c00: ohci_generic usb@9a83c00: Failed to get clocks (ret=-19)
Port not available.
Bus usb@9a83e00: ehci_generic usb@9a83e00: Failed to get clocks (ret=-19)
Port not available.
