Looking into pciexp_get_ext_cap_offset() it seems a little hackish
and prone to endless loops. Either it should limit the loop or bail
out when pci_read_config32() returns 0xffffffff, meaning "Unsupported
Requests".
This commit fixes an endless loop when the queried PCIe device is
downstream of a legacy PCI bus which doesn't support extended config
space, thus pci_read_config32() will return 0xffffffff, for example,
the combination below with CONFIG_PCIEXP_SUPPORT_RESIZABLE_BARS
enabled.

Recent changes to both coreboot and edk2 means that UefiPayloadPkg
seems to work on all hardware. It has been tested on:
* Intel Core 2nd, 3rd, 4th, 5th, 6th, 8th, 8th, 9th, 10th,
11th and 12th generation processors
* Intel Small Core BYT, BSW, APL, GLK and GLK-R processors
* AMD Stoney Ridge and Picasso
This includes the problematic Lenovo X230s. The most likely fixes are:
* Configuring the PCI Base and Length in edk2
* Fixes to the HostBridgeLib in edk2
* Adjustment to the SD/eMMC initialisation timeout
This means we can now remove the already deprecated option for
CorebootPayloadPkg and the legacy 8254 timer build option.
