PCI: aardvark: Fix PCIe Max Read Request Size setting

There is an obvious typo issue in the definition of the PCIe maximum
read request size: a bit shift is directly used as a value, while it
should be used to shift the correct value.

Fixes: 8c39d710363c1 ("PCI: aardvark: Add Aardvark PCI host controller driver")
