Marek Behún 4bb5399c1c PCI: aardvark: Read all 16-bits from PCIE_MSI_PAYLOAD_REG ...

commit 95997723b6402cd6c53e0f9e7ac640ec64eaaff8 upstream.

The PCIE_MSI_PAYLOAD_REG contains 16-bit MSI number, not only lower
8 bits. Fix reading content of this register and add a comment
describing the access to this register.
