Introduce a new clock workaround function used by DT reference code on the mach-shmobile subarchitecture. The new function shmobile_clk_workaround() is used to configure clkdev to allow DT and platform devices to coexist. It is possible for the DT reference board code to also request enabling of the clock in case the driver does not implement clock control.
