In SDX55, the IPC bits are located in the APCS GCC block. Also, this block
can provide clock functionality. Hence, add support for IPC with correct
offset and name of the clock provider.

The Qualcomm ipq6018 has apcs block, add compatible for the same. Also,
the ipq6018 apcs provides a clock functionality similar to msm8916 but
the clock driver is different.

Some apcs mailbox devices supports a clock driver, the compatible
strings of devices supporting clock driver along with the clock driver
name are maintained in a separate structure within the mailbox driver.
And the clock driver is added based on device match.
With increase in number of devices supporting the clock feature move the
clock driver name inside the driver data. so that we can use a single
API to get the register offset of mailbox driver and clock driver name
together, and the clock driver will be added based on the driver data.
