pcmcia/sa1100: don't put machine specific init functions in .init.text

These are called by sa11x0_drv_pcmcia_probe (which is marked now with
__devinit) so they can go to .devinit.text now, too.

This fixes:

	WARNING: drivers/pcmcia/sa1100_cs.o(.text+0x10): Section mismatch in reference from the function sa11x0_drv_pcmcia_probe() to the function .init.text:pcmcia_simpad_init()
	The function sa11x0_drv_pcmcia_probe() references
	the function __init pcmcia_simpad_init().
	This is often because sa11x0_drv_pcmcia_probe lacks a __init
	annotation or the annotation of pcmcia_simpad_init is wrong.

and a similar warning for pcmcia_collie_init, pcmcia_cerf_init,
pcmcia_h3600_init and pcmcia_shannon_init.

While at it mark pcmcia_assabet_init with __devinit, too.
