clk: renesas: mstp: Remove obsolete clkdev registration

After the DT conversion of SH-Mobile and Armadillo-800-EVA display
support, all devices are registered from DT, so we can remove the
registration of clkdevs.

Add the missing #include <linux/slab.h>, which was included implicitly
through <linux/clkdev.h> before.
