macio: re-add TRIM support

Commit bd4214fc dropped TRIM support by mistake. Given it is still
advertised to the host when using a drive with discard=on, this cause
the IDE bus to hang when the host issues a TRIM command.

This patch fixes that by re-adding the TRIM code, ported to the new
new DMA implementation.
