staging: vt6656: Change variable type to bool

The variables bMultiBand and bKeyTableFull are only assigned the
values true and false. Change its type to bool.

The simplified semantic patch that find this problem is as
follows (http://coccinelle.lip6.fr/):

@exists@
type T;
identifier b;
@@
- T
+ bool
  b = ...;
  ... when any
  b = \(true\|false\)
