[PATCH 07/14] mailbox: pcc: Move pcc_mbox_ioremap() before pcc_mbox_request_channel()

[Sudeep Holla <sudeep.holla@arm.com>]

In order to add support of mapping the generic communication shared
memory region in the PCC mailbox driver when the PCC channel is requested,
we need to move pcc_mbox_ioremap() before pcc_mbox_request_channel().

No functional change.
