mfd: 88pm860x: Fix section mismatch warning

WARNING: drivers/built-in.o(.data+0x1e3c8): Section mismatch in
reference from the variable bk_devs to the variable
.devinit.data:bk0_resources
The variable bk_devs references
the variable __devinitdata bk0_resources
If the reference is valid then annotate the
variable with __init* or __refdata (see linux/init.h) or name the
variable:
*driver, *_template, *_timer, *_sht, *_ops, *_probe, *_probe_one,
*_console

So add __devinitdata on bk_devs, led_devs & reg_devs.
