A lot more generic cam related things were done in mmc_sim so this
simplifies the driver a lot.

- 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.

rtsx copied code from sdhci, and has the same wakeup race bug that was
fixed in 35547df5c7, so apply a similar fix here.

(cherry picked from commit 9339e7c0bd)
This driver provides support for Realtek PCI SD card readers. It attaches
mmc(4) bus on card insertion and detaches it on card removal. It has been
tested with RTS5209, RTS5227, RTS5229, RTS522A, RTS525A and RTL8411B. It
should also work with RTS5249, RTL8402 and RTL8411.
