[PATCH v4 2/9] ipa: rkisp1: Pass parameters buffer format to IPA module

[Laurent Pinchart]

The rkisp1 driver supports two formats for the ISP parameters buffer,
the legacy fixed format and the new extensible format. In preparation of
support for the new format, pass the parameters buffer format from the
pipeline handler to the IPA module and store it.
