arm64: dts: ti: k3-am69-aquila: Change main_spi0/2 CS to GPIO mode

Hardware chip select does not work correctly on main_spi0 and
main_spi2 controllers. Testing shows main_spi2 loses CS state
during runtime PM suspend, while main_spi0 cannot drive CS HIGH
when bus is idle.

Use GPIO-based chip select for both controllers.
