Subject: [PATCH] ARM: imx: Annotate imx7d_enet_init() as __init

After a recent LLVM change [1] that deduces __cold on functions that
only call cold code (such as __init functions), there is a section
mismatch warning from imx7d_enet_init(), which got moved
to .text.unlikely. as a result of that optimization:

  WARNING: modpost: vmlinux: section mismatch in reference:
imx7d_enet_init+0x20 (section: .text.unlikely.) -> imx7d_enet_clk_sel
(section: .init.text)

Drop the inline keyword (which does not guarantee inlining) and
replace it with __init, as imx7d_enet_init() is only called from __init
code, which clears up the warning.
