[RFC PATCH v2 05/21][SeaBIOS] pciinit: Fix pcimem_start value

[Vasilis Liaskovitis <vasilis.liaskovitis@profitbricks.com>]

In order to hotplug memory between RamSize and BUILD_PCIMEM_START, the pci
window needs to start at BUILD_PCIMEM_START (0xe0000000).
Otherwise, the guest cannot online new dimms at those ranges due to pci_root
window conflicts. (workaround for linux guest is booting with pci=nocrs)
