include/hw/pci/pcie_host: Correct PCIE_MMCFG_SIZE_MAX
According to 7.2.2 in [1] bit 27 is the last bit that can be part of the
bus number, this makes the ECAM max size equal to '1 << 28'. This patch
restores back this value into the PCIE_MMCFG_SIZE_MAX define (which was
changed in commit 58d5b22bbd5 ("ppc4xx: Add device models found in PPC440
core SoCs")).
