cd_gpio is floating on some devices, then there is a possiblity
that a false CARD_DETECT toggle is created when software starts to
resume SD card from power collapse at the same time. SD driver resume
will fail due to collision.

Current code to enable CoreSight NIDnT serial wire debug trace mode
is incorrectly disabling all enabled components even on success. Fix
this to get trace in serial wire debug mode.

As the NIDnT hardware sense function use the same detecting gpio
with SD card, if the NIDnT driver directly use this gpio, it will
result in the sdcard can't use any more, need disable this feature

If gpio entries are not present in dt file, the resource query
function returns negative value for gpio count. Currently data
type for gpio count is unsigned int which wraps around and gives
positive result for negative value that causes failure while
probing the driver. Modify gpio count data type to integer and
check if it is positive before using it.
