Subject: [PATCH v4 07/18] PCI: dwc: Add braces to the multi-line if-else statements

In accordance with [1] if there is at least one multi-line if-else
clause in the statement, then each clause will need to be surrounded by
the braces. The driver code violates that coding style rule in a few
places. Let's fix it.
