[ Upstream commit acaf892ecbf5be7710ae05a61fd43c668f68ad95 ]
Many of the sh CPU-types have their own plat_irq_setup() and arch_init_clk_ops() functions, so these same (empty) functions in arch/sh/boards/of-generic.c are not needed and cause build errors.
If there is some case where these empty functions are needed, they can be retained by marking them as "__weak" while at the same time making builds that do not need them succeed.
Fixes these build errors:
