ipa: rkisp1: Drop unnecessary forward declarations and includes

Forward declarations of IPACameraSensorInfo and inclusion of
linux/rkisp1-config.h are not needed in headers that use them only for
arguments to functions defined by the Algorithm base class, as inclusion
of algorithm.h will bring the necessary declarations for function
arguments. Drop them.
