Subject: [PATCH v6 22/23] media: rzg2l-cru: Move register definitions to a separate file
From: Lad Prabhakar <prabhakar.mahadev-lad.rj@...renesas.com>
Move the RZ/G2L CRU register definitions from `rzg2l-video.c` to a
dedicated header file, `rzg2l-cru-regs.h`. Separating these definitions
into their own file improves the readability of the code.
