libpayload/pci: Add pci_map_bus function for Qualcomm platform

Browse Source 
Add 'pci_map_bus' function and PCIE_QCOM config for Qualcomm platform.

BUG=b:182963902,b:216686574,b:181098581
TEST=Verified on Qualcomm sc7280 development board with NVMe endpoint
(Koixa NVMe, Model-KBG40ZPZ256G with FW AEGA0102). Confirmed NVMe is
getting detected in response to 'storage init' command in depthcharge
CLI prompt.

Output logs:
 ->dpch: storage init
   Initializing NVMe controller 1e0f:0001
   Identified NVMe model KBG40ZPZ256G TOSHIBA MEMORY
   Added NVMe drive "NVMe Namespace 1" lbasize:512, count:0x1dcf32b0
  *  0: NVMe Namespace 1
    1 devices total

Also verified NVMe boot path that is depthcharge is able to load the
kernel image from NVMe storage.
