media: synopsys: Add support for i.MX95

Add support for the i.MX95 MIPI CSI-2 receiver. The i.MX95 variant is
nearly identical to i.MX93, with the main difference being the use of
IDI (Image Data Interface) instead of IPI (Image Pixel Interface).
However, the IDI interface is transparent to software, requiring only
a different register map definition while sharing the same PHY control
functions with i.MX93.
