[PATCH] V4L1: make PMS not autoprobe when builtin.

[Rene Herman]

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 moreover.
