Subject: [PATCH] clk: sunxi-ng: Use of_device_get_match_data()

From: Rosen Penev <[email-masked]>
Date: Mon, 18 May 2026 17:39:50 -0700

Use of_device_get_match_data() to fetch the RTC CCU match data directly
instead of open-coding an of_match_device() lookup.

This also lets the driver drop the of_device.h include.
