ARM: fix section mismatch warnings in Versatile Express

WARNING: vmlinux.o(.text+0xbf30): Section mismatch in reference from the function v2m_timer_init() to the function .init.text:sp804_clocksource_init()
The function v2m_timer_init() references
the function __init sp804_clocksource_init().
This is often because v2m_timer_init lacks a __init
annotation or the annotation of sp804_clocksource_init is wrong.

WARNING: vmlinux.o(.text+0xbf3c): Section mismatch in reference from the function v2m_timer_init() to the function .init.text:sp804_clockevents_init()
The function v2m_timer_init() references
the function __init sp804_clockevents_init().
This is often because v2m_timer_init lacks a __init
annotation or the annotation of sp804_clockevents_init is wrong.

WARNING: vmlinux.o(.text+0xc524): Section mismatch in reference from the function ct_ca9x4_init() to the function .init.text:l2x0_init()
The function ct_ca9x4_init() references
the function __init l2x0_init().
This is often because ct_ca9x4_init lacks a __init
annotation or the annotation of l2x0_init is wrong.

WARNING: vmlinux.o(.text+0xc530): Section mismatch in reference from the function ct_ca9x4_init() to the function .init.text:clkdev_add_table()
The function ct_ca9x4_init() references
the function __init clkdev_add_table().
This is often because ct_ca9x4_init lacks a __init
annotation or the annotation of clkdev_add_table is wrong.

WARNING: vmlinux.o(.text+0xc578): Section mismatch in reference from the function ct_ca9x4_init() to the (unknown reference) .init.data:(unknown)
The function ct_ca9x4_init() references
the (unknown reference) __initdata (unknown).
This is often because ct_ca9x4_init lacks a __initdata
annotation or the annotation of (unknown) is wrong.

Fix these by making ct_ca9x4_init() and v2m_timer_init() both __init.
