[PATCH v3 2/2] staging: media: tegra-video: move tegra20_vip_soc declaration to vip.h

[Sun Jian <sun.jian.kdev@gmail.com>]

tegra20_vip_soc is shared across translation units but is currently
declared via an extern in vip.c. Move the declaration to vip.h so users get
it via the header and we avoid extern declarations in .c files, matching
the pattern already used by tegra20_vi_soc and tegra210_vi_soc.
