TQM5200: fix default IDE reset level
Before the first call of ide_reset(), the level of the IDE reset signal on the TQM5200 is low (reset asserted). This patch sets the default value to high (reset not asserted). Currently this patch fixes no real problem, but it is cleaner to assert the reset signal only on demand, and not permanently. Signed-off-by: Martin Krause <martin.krause@tqs.de>
