V4L/DVB (8727): V4L1: make PMS not autoprobe when builtin.

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.
