The DWC controller used in the Qcom Platforms are capable of addressing the
MSIs generated from 8 different endpoints each with 32 vectors (256 in
total). Currently the driver is using the default value of addressing the
MSIs from 1 endpoint only. Extend it by passing the MAX_MSI_IRQS to the
num_vectors field of pcie_port structure.
