Some ti/k3-am62x-* overlays no longer apply to am62a platform. We can
keep ti/k3-am62x-sk but it will cause confusion since at least the
following overlays no longer apply to am62a:

k3-am62x-sk-dmtimer-pwm.dtso
k3-am62x-sk-mcan.dtso

Is there some kind of blacklist for overlays not to be included for a
platform?
