[PATCH 08/21] media: i2c: it6625: make the audio sampling-rate table static const

[Hermes Wu via B4 Relay]

From: Hermes Wu <Hermes.wu@xxxxxxxxxx>

s_fsid_map in get_audio_sampling_rate() is a fixed lookup table
rebuilt on the stack on every call; make it static const so it's
emitted once as read-only data instead. While touching this
declaration, move it ahead of the plain int locals per reverse
fir-tree ordering.
