V4L1: make PMS not autoprobe when builtin.
From: Rene Herman <rene.herman@keyaccess.nl>
The old Mediavision Pro Movie Studio legacy ISA V4L1 driver was found to
hang the boot during Ingo Molnar's testing of randconfig kernels. Have it
require a "pms.enable=1" kernel parameter to enable the driver when
builtin which avoids such problems.
This is a deprecated and, very likely, unused driver. Nothing changes
modular behaviour moreover.
