Subject: staging: fsl-dpaa2/eth: Fix incorrect casts
Git-commit: 75c583ab9709692a60871d4719006391cde8dc1d
Patch-mainline: v4.17-rc1
References: fate#326530,fate#326531,fate#326535,fate#326538,fate#326539
The DPAA2 Ethernet driver incorrectly assumes virtual addresses
are always 64b long, which causes compiler errors when building
for a 32b platform.
Fix this by using explicit casts to uintptr_t where necessary.
