dwmmc: Handle the card detect interrupt

The driver used to always add the mmc device as it's child even
it no card was detected. Add a function that will detect if the
card is present or not and that will attach/detach the mmc device.
The function is either call on attach (as we won't have the interrupt
fired) or from two taskqueues. The first taskqueue will directly call
the function when the sdcard was present and is now removed and the other
one will delay a bit the attach when we didn't had a card and now have one.
This is mostly based on comments from the sdhci driver where it describe
a situation when the CD pin is detected before the others pins are connected.

Add support for the DesignWare MMC hardware in the HiSilicon hi6220. This
SoC is used in the HiKey board from 96boards.

Currently on the SD card is working on the HiKey, as such devices 0 and 2
will need to be disabled, for example by adding the following to
loader.conf:

hint.hisi_dwmmc.0.disabled=1
hint.hisi_dwmmc.2.disabled=1

Relnotes: yes (Hikey board booting)
