media: uapi: Convert Amlogic C3 to V4L2 extensible params

With the introduction of common types for extensible parameters
format, convert the c3-isp-config.h header to use the new types.

Factor-out the documentation that is now part of the common header
and only keep the driver-specific on in place.

The conversion to use common types doesn't impact userspace as the
new types are either identical to the ones already existing in the
C3 ISP uAPI or are 1-to-1 type convertible.
