[PATCH 01/42] drm/mediatek: Rename OVL format naming

[AngeloGioacchino Del Regno]

From: Paul-pl Chen <paul-pl.chen at mediatek.com>

Rename format arrays from mt8173_formats[] to mt8173_ovl_formats[]
to explicitly indicate that these format definitions are specific
to OVL (Overlay) components.

This naming improvement is necessary because MT8196 introduces new
display components (EXDMA, BLENDER, OUTPROC) that support different
format capabilities than OVL. Without clear naming, it becomes
ambiguous which formats apply to which component type.

Examples of format differences between components:
- EXDMA supports 10-bit RGB formats that some OVL variants don't
- BLENDER has different YUV handling requirements
- Component-specific format conversion capabilities vary

The explicit naming:
- Prevents confusion when debugging format-related issues
- Makes it immediately clear which component a format array belongs to
- Improves code searchability (grep for "ovl_formats")
- Follows consistent naming convention for component-specific definitions
- Prepares for adding exdma_formats[], blender_formats[] arrays

This is a preparatory patch for MT8196 component support, which
requires clear distinction between OVL formats and EXDMA/BLENDER
formats to avoid applying incorrect format configurations.
