When the TUI use case starts, HLOS prepares for sharing the HW
by collecting the register io spaces and IRQ lines from all the
participating subdrivers before the switch. This change
adds necessary hook in the VM event framework, so that
subdrivers can provide their callback functions while
registering for events. It also adds necessary helpers
in the sde io util to parse and populate the IO memory
region that needs to be shared.

the VM switch. This change provides framework for display dependent
drivers like DSI, DP and RSCC to register for various VM switch
event hooks.
The following hooks to provided through msm_vm_ops:
post_hw_acquire: invoked before the first frame push after gaining
HW access.
pre_hw_release: invoked after the last frame commit before releasing
the HW.
check: check with vm clients for their readiness for HW
releasing.
