am33x-cm3: remove

This is currently unused and not working anyway, since the used upstream
kernel loads am335x-pm-firmware.elf and not am335x-pm-firmware.bin [0].

The last downstream patches using the latter were removed with e4eef7e6.

Remove it instead of fixing it since the rtc-only sleep state can even
damage the hardware [1].
