PCI: histb: Constify dw_pcie_host_ops structure

JuliaLawall · Lorenzo Pieralisi · commit b69f4abc125f · 2018-11-08T13:54:44.000Z
The dw_pcie_host_ops structure is only stored in the ops field
of a pcie_port structure, and this field is const, so make the
dw_pcie_host_ops structure const as well.

Done with the help of Coccinelle.
