Instead a getting only one common device "/dev/ion" for

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. Jordan -- The Qualcomm Innovation Center, Inc. is a member of Code Aurora Forum, a Linux Foundation Collaborative Project
