From: Nagabhushana Netagunte <nagabhushana.netagunte@xxxxxx>
add dm365 IPIPE hardware support. IPIPE is the hardware IP which
implements the functionality required for resizer, previewer and
the associated feature support. This is built along with the vpfe
driver, and implements hardware setup including coeffcient
programming for various hardware filters, gamma, cfa and clock
enable.
