soc/qualcomm/sc7280: Enable PCIe driver
Enable PCIe functionality on sc7280 and supply all the needed data
for PCIe generic platform driver.
BUG=b:182963902,b:216686574,b:181098581
TEST=Verified on Qualcomm sc7280 development board with NVMe card
(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.
