Subject: [PATCH 6/6] riscv: dts: thead: change TH1520 SPI node to use clock
 controller

From: Drew Fustini <dfustini@...storrent.com>

Change the clock property in the TH1520 SPI controller node to a clock
provided by AP_SYS clock controller.

Remove spi_clk fixed clock reference from BeagleV Ahead and LPI4a dts.
