media: nxp: imx8-isi: Add virtual channel support

Browse source 
The ISI supports different numbers of virtual channels depending on the
platform. i.MX95 supports 8 virtual channels, and i.MX8QXP/QM support 4
virtual channels. They are used in multiple camera use cases, such as
surround view. Other platforms (such as i.MX8/MN/MP/ULP/91/93) don't
support virtual channels, and the VC_ID bits are marked as read-only.
