[PATCH] i2c-pxa: fix compiler warning, due to missing const

[Marc Kleine-Budde <mkl-bIcnvbaLZ9MEGnE8C9+IrQ@public.gmane.org>]

This patch adds the missing const to "struct platform_device_id" to fix
this warning:

/home/frogger/pengutronix/linux/linux-2.6/drivers/i2c/busses/i2c-pxa.c:
In function 'i2c_pxa_probe':
/home/frogger/pengutronix/linux/linux-2.6/drivers/i2c/busses/i2c-pxa.c:1004:
warning: initialization discards qualifiers from pointer target type
