Subject: [PATCH] avcodec/dct: Make declarations and definitions match

GCC considers declarations using a parameter of pointer
type (or equivalently a parameter using an array of unspecified
dimensions) to be inconsistent with a declaration using
a known-length array type and emits a -Warray-parameter warning
for several ff_j_rev_dct* functions for this.

This patch makes the declarations match the actual definitions
to suppress these (IMO nonsensical) warnings.
