kernel: fix *-gpio-custom module unloading
Unloading and reloading the modules fails, as platform_device_put() does not
release resources fully.
root@OpenWrt:/# insmod i2c-gpio-custom bus0=0,18,0,5
[ 196.860620] Custom GPIO-based I2C driver version 0.1.1

[ 197.513200] kobject_add_internal failed for i2c-gpio.0 with -EEXIST, don't try to register things with the same name in the same directory.
This patch fixes it by replacing platform_device_put() to
platform_device_unregister().
