TQM5200: fix default IDE reset level

Browse Source 
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.
