rtsx: Call taskqueue sooner, adjust DELAY(9) calls, add an inversion heuristic

- Some configurations, e.g. HP EliteBook 840 G3, come with a dummy card
in the card slot which is detected as a valid SD card.  This added long
timeout at boot time.  To alleviate the problem, the default timeout is
reduced to one second during the setup phase. [1]

- Some configurations crash at boot if rtsx(4) is defined in the kernel
config.  At boot time, without a card inserted, the driver found that
a card is present and just after that a "spontaneous" interrupt is
generated showing that no card is present.  To solve this problem,
DELAY(9) is set to one quarter of a second before checking card presence
during driver attach.

- As advised by adrian, taskqueue and DMA are set up sooner during
the driver attach.  A heuristic to try to detect configuration needing
inversion was added.
