disp: msm: add capability to dynamically update the transfer time

This change adds a connector OP, that will be used to update frame
transfer time dynamically at the request from user space.

It also adds parsing for new device tree entries that set the minimum
and maximum trasnfer times on a mode basis. These min and max transfer
times are also published to userspace through the connector mode info
capabilities blob.
