[PATCH OLK-6.6 521/602] media: i2c: imx219: Replace register addresses with macros

From: Laurent Pinchart laurent.pinchart@ideasonboard.com

stable inclusion from stable-v6.6.2 commit ae6f196a8de96e4102b85a8e0ca01c52279a1ccc category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I8IW7G

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=...

--------------------------------

[ Upstream commit 1c9083565a4698ff072f1209e9450ff6c305e2cc ]

Define macros for all the known registers used in the register arrays, and use them to replace the numerical addresses. This improves readability.
