Subject: [PATCH 3/6] riscv: dts: thead: change TH1520 mmc nodes to use
clock controller
From: Drew Fustini <dfustini@...storrent.com>
Change the clock property in the TH1520 mmc controller nodes to a clock
provided by AP_SYS clock controller.
Remove sdhci fixed clock reference from BeagleV Ahead and LPI4a dts.
