  There is no need to have dt-compat.c compiled for SAMA7G5 and SAM9X60
as there is no in kernel device tree that could use it. Thus avoid
compiling dt-compat.c for them.

Isn't it time to drop dt-compat.c? I was going to send a patch after 6.1
is released

My assumption was that we need to guarantee that old device trees will
still work with newer kernels. Should we guarantee this only for a limited
period of time?

Applied to clk-microchip, thanks!
