ARM: pxa: avoid section mismatch warning

BugLink: https://bugs.launchpad.net/bugs/1818813

[ Upstream commit 88af3209 ]

WARNING: vmlinux.o(.text+0x19f90): Section mismatch in reference from the function littleton_init_lcd() to the function .init.text:pxa_set_fb_info()
The function littleton_init_lcd() references
the function __init pxa_set_fb_info().
This is often because littleton_init_lcd lacks a __init
annotation or the annotation of pxa_set_fb_info is wrong.

WARNING: vmlinux.o(.text+0xf824): Section mismatch in reference from the function zeus_register_ohci() to the function .init.text:pxa_set_ohci_info()
The function zeus_register_ohci() references
the function __init pxa_set_ohci_info().
This is often because zeus_register_ohci lacks a __init
annotation or the annotation of pxa_set_ohci_info is wrong.

WARNING: vmlinux.o(.text+0xf95c): Section mismatch in reference from the function cm_x300_init_u2d() to the function .init.text:pxa3xx_set_u2d_info()
The function cm_x300_init_u2d() references
the function __init pxa3xx_set_u2d_info().
This is often because cm_x300_init_u2d lacks a __init
annotation or the annotation of pxa3xx_set_u2d_info is wrong.
