staging: vt6655: Replace VNSvInPortB with ioread8

Replace macro VNSvInPortB with ioread8. Avoid cast of the return
value is possible with one exception.
The name of macro and the arguments use CamelCase which
is not accepted by checkpatch.pl

Since there are more than one checkpatch issue per line,
more steps are rquired to fix.
