[PATCH RFC v3 7/7] riscv: dts: thead: update TH1520 dma and timer nodes to use clock controller

From: Drew Fustini
Date: Tue May 07 2024 - 00:59:28 EST


Change the dma-controller and timer nodes to use the APB clock provided
by the AP_SUBSYS clock controller.

Remove apb_clk reference from BeagleV Ahead and LPI4a dts.
