Newer SPMI controller (v7) found on Qualcomm platforms
provide support for multiple bus master. So add support
for multiple masters in both the generic framework and
the Qualcomm SPMI PMIC Arbiter driver.

Currently, the DT child nodes of the spmi controller node
are the slave devices connected to the bus. This patchset
proposes another layer of nodes in between. They would be
the master bus nodes. They will not be populated as separate
devices as they need to share register regions with the controller.
