media: i2c: it6625: drop the private CSI-format name table

Browse Source 
it6625_csi_format_name(), used only by it6625_log_status(), maintains
a driver-local name table for a value V4L2 already exposes as a
media-bus format code. No in-kernel helper converts MEDIA_BUS_FMT_*
codes to printable names, so report the raw media-bus code as %#x
instead. it6625_log_status() now snapshots it6625->mbus_fmt_code
(the value actually used elsewhere as the driver's representation of
the current format) under it6625_lock instead of the separate
csi_format field.
