ARM: omap: hwmod: fix section mismatch warnings

Older compilers choose not to inline _setup_clkctrl_provider(),
leading to a harmless warning:

WARNING: vmlinux.o(.text+0x27b34): Section mismatch in reference from the function _setup_clkctrl_provider() to the function .init.text:memblock_virt_alloc_try_nid()
The function _setup_clkctrl_provider() references
the function __init memblock_virt_alloc_try_nid().
This is often because _setup_clkctrl_provider lacks a __init
annotation or the annotation of memblock_virt_alloc_try_nid is wrong.

This annotates it as __init as well, which lets the linker
see that it is actually correct.
