media: renesas: vsp1: rwpf: Support operations with IIF

Browse source 
When the RPF/WPF units are used for ISP interfacing through
the IIF, the set of accessible registers is limited compared to
the regular VSPD operations.

Support ISP interfacing in the rpf and wpf entities by checking if
the pipe features an IIF instance and writing only the relevant
registers.
