[PATCH v2 01/14] libcamera: v4l2_subdevice: Rename V4L2SubdeviceFormatInfo

[Kieran Bingham]

Quoting Laurent Pinchart (2024-03-15 00:16:00)
> The V4L2SubdeviceFormatInfo structure contains information about a media
> bus format, not a V4L2 subdevice format. Rename it to MediaBusFormatInfo
> to clarify its purpose. Rename the formatInfoMap map accordingly.
