mailbox: pcc: Use acpi_os_ioremap() instead of ioremap()
The Platform Communication Channel (PCC) mailbox driver currently uses
ioremap() to map channel shared memory regions. However it is preferred
to use acpi_os_ioremap(), which is mapping function specific to EFI/ACPI
defined memory regions. It ensures that the correct memory attributes
are applied when mapping ACPI-provided regions.
While at it, also add checks for handling any errors with the mapping.
