Subject: [PATCH] media: amphion: correct the unspecified color space

References: bsc#1012628

Patch-mainline: 6.2.3

Git-commit: 809060c8a357e020010dd8f797a5efd3c5432b13

[ Upstream commit 809060c8a357e020010dd8f797a5efd3c5432b13 ]

in the E.2.1 of Rec. ITU-T H.264 (06/2019),

0 of colour primaries is reserved, and 2 is unspecified.

driver can map V4L2_COLORSPACE_LAST to 0,

and map V4L2_COLORSPACE_DEFAULT to 2.

v4l2_xfer_func and v4l2_ycbcr_encoding are similar case.
