Bjorn Helgaas e3a1698b1e PCI: iproc: Hard-code PCIe capability offset instead of searching
We know where the PCIe capability lives in the host bridge's config space;
in fact, we already hard-coded the offset of the Link Control 2 register.

The hard-coded Link Control 2 offset was 0xdc.  Link Control 2 is at offset
0x30 into the PCIe capability, so the capability itself must be at
0xdc - 0x30 = 0xac.

Hard-code the PCIe capability offset, which means we don't have to search
for it and we can use the standard definitions for registers within the
capability.

No functional change intended.

Bjorn Helgaas 6d76833c52 PCI: iproc: Remove redundant null pointer checking
The callers never pass a null "pcie" pointer (they check for kzalloc
failure), so we don't need to check here.  The bus driver should never call
the probe function with a null ->dev pointer, so we don't need to check
that either.  No functional change intended.
