Instead a getting only one common device "/dev/ion" for all the heaps this patch allow to create one device entry ("/dev/ionX") per heap. Getting an entry per heap could allow to set security rules per heap and global ones for all heaps.

Allocation requests will be only allowed if the mask_id match with device minor. Query request could be done on any of the devices.

Ion devices are parentless so it is need to add platform_bus as parent and platform_bus_type as bus to be put in /sys/device/paltform.

nit: paltform -> platform.
