MIPS: DB1200: PCMCIA card detection must not be auto-enabled.

Browse Source 
Same issues as SD card detection:  One of both is always triggering and the
handlers take care to shut it up and enable the other.  To avoid messages
about "unbalanced interrupt enable/disable" they must not be automatically
enabled when initally requested.

This was not an issue with the db1200_defconfig due to fortunate timings;
on a build without network chip support the warnings appear.
