[PATCH 1/3] media: rtl2832: make regmap_config static const

This struct was previously carried over in the rtl2832_dev struct, even
though it was used only once at probe-time, using purely static data.

This reduces the size of the rtl2832_dev struct by 192 B, by putting it
in the .rodata section instead.
