This patch fixes coding style issues reported by checkpatch. The vast
majority of changes in this patch are removing spaces before opening
parenthesis, but in some cases, a few additional changes are made to fix
other coding style issues.

These additional changes are:

 - Spaces around >> on line 50.
 - On line 55 a call to ehci_dbg reduced to a single line.
 - sizeof operands surrounded with parenthesis on lines 877, 883, 889
   and 901.
