[MIPS] Alchemy: Fix ids in Alchemy db dma device table
0 is a valid device id (DSCR_CMD0_UART0_TX), so we can't use it to mark an empty entry in the device table. Use ~0 instead and search for id ~0 when looking for a free entry. Signed-off-by: Wolfgang Ocker <weo@reccoware.de> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
