mailbox: mpfs-mbox: fix MMIO mapping calculation
Correct the MMIO mapping size calculation, which
previously relied on an invalid start/end subtraction.
This change corrects a functional bug and cleans up the driver without
altering its behavior.
Fixes: 111e9bf6a5ac ("mailbox: add PolarFire SoC mailbox driver")
