[PATCH] pcie-rcar: fix some checkpatch warnings

[Sergei Shtylyov <sergei.shtylyov@cogentembedded.com>]

The R-Car PCIe driver causes 13 warnings from scripts/checkpatch.pl --
let's fix at least 10 easier ones:

- line over 80 characters;

- blank line missing after declarations;

- statements not starting on a tabstop.

Signed-off-by: Sergei Shtylyov <sergei.shtylyov@cogentembedded.com>

---
The patch is against the 'next' branch of Bjorn Helgaas' 'pci.git' repo plus
two patches  posted  earlier...
