Claude review: drm/msm/dsi: add DSI version >= comparison helper

Patch Review

**Minor issue with the helper semantics:**

```c
+static bool msm_dsi_host_version_ge(struct msm_dsi_host *msm_host,
+				    u32 major, u32 minor)
+{
+	return msm_host->cfg_hnd->major == major &&
+	       msm_host->cfg_hnd->minor >= minor;
+}
```

This function checks `major == major && minor >= minor`, which means it is NOT a true "greater than or equal" across major versions — it only works when the major version matches exactly. If a future DSI controller had `major = 0x04`, this would return `false` even though that version is strictly greater than any `0x03` version.

For the current use (all 6G controllers share `MSM_DSI_VER_MAJOR_6G == 0x03`), this works fine, but the name `_ge` is slightly misleading. The cover letter mentions "msm_dsi_host_version_is_gt per Konrad" but the implementation is `_ge` (greater-or-equal), which is what the code actually needs. This inconsistency in naming between cover letter and code is minor.

The refactoring of `msm_dsi_host_is_wide_bus_enabled` to use the new helper is a clean simplification.
