omap3xxx_prm_enable_io_wakeup() is marked __init, but its caller is not, so
we get a warning with clang-8:
WARNING: vmlinux.o(.text+0x343c8): Section mismatch in reference from the function omap3xxx_prm_late_init() to the function .init.text:omap3xxx_prm_enable_io_wakeup()
The function omap3xxx_prm_late_init() references
the function __init omap3xxx_prm_enable_io_wakeup().
This is often because omap3xxx_prm_late_init lacks a __init
annotation or the annotation of omap3xxx_prm_enable_io_wakeup is wrong.
When building with gcc, omap3xxx_prm_enable_io_wakeup() is always
inlined, so we never noticed in the past.

That's unfortunate, both omap3xxx_prm_enable_io_wakeup and
omap3xxx_prm_late_init are only ever called at init time (by prm_late_init
which is also __init annotated). However the omap3xxx_prm_ll_data
structure containing the late_init has a life beyond init. Otherwise I
would have suggested annotating omap3xxx_prm_late_init.
