[PATCH v2 35/65] PCI: dwc: designware: Get device pointer at the start of dw_pcie_host_init()

[Andrey Smirnov]

Port of a Linux commit 40f67fb2c384fe12741aa35010d62bfe8c98286c

  No functional change. Get device pointer at the beginning of
  dw_pcie_host_init() instead of getting it all over dw_pcie_host_init().
  This is in preparation for splitting struct pcie_port into host and core
  structures (once split pcie_port will not have device pointer).
