[PATCH] w1:masters/w1-gpio.c: fix error using "__devinit" and "__devexit"

w1:masters/w1-gpio.c: fix error using "__devinit" and "__devexit"

we should use "__devinit" to mark the probe function, "__devexit" to
mark the remove function, and "__devexit_p" to mark the pointer to the
remove function.

the error was found by the following compilation warning:
WARNING: drivers/w1/masters/w1-gpio.o(.data+0x0): Section mismatch in
reference from the variable w1_gpio_driver to the function
.init.text:w1_gpio_probe()
The variable w1_gpio_driver references
the function __init w1_gpio_probe()
If the reference is valid then annotate the
variable with __init* or __refdata (see linux/init.h) or name the variable:
*_template, *_timer, *_sht, *_ops, *_probe, *_probe_one, *_console
