Sudeep Holla 7002ca237b mailbox: arm_mhu: Add ARM MHU doorbell driver 
The MHU drives the signal using a 32-bit register, with all 32 bits
logically ORed together. The MHU provides a set of registers to enable
software to set, clear, and check the status of each of the bits of this
register independently. The use of 32 bits for each interrupt line
enables software to provide more information about the source of the
interrupt. For example, each bit of the register can be associated with
a type of event that can contribute to raising the interrupt.

This patch adds a separate the MHU controller driver for doorbel mode
of operation using the extended DT binding to add support the same.
