Although We can add the sdmmc node, shouldn't enable it.
Since the sdmmc is reusing the same pin with uart2.
Unfortunately, the uart2 is used by the debug port, so that will cause
the debug information can't display on console if enabling the sdmmc.
As we have supported the sdmmc (sd card) on hardware for kylin board.
So, maybe we can have the sdmmc node in kylin dts, not to enable it.
Anyway, you only need add the okay status if someone want to enable the
sdmmc.
e.g.
if you use the adb to debug with android os.
You can add the
status = "okay" to enable the sdmmc for sd card working.
The default status is disabling it.

So the reset and power of WlAN chip can be handled in mmc power sequence.
On the module itself this is one of these, that should can be handled

At the moment, our fault injection is pretty limited. We always
generate a SYNC exception into EL1, as if the fault was actually
from EL1h, no matter how it was generated.
This is obviously wrong, as EL0 can generate faults of its own
(not to mention the pretty-much unused EL1t mode).
This patch fixes it by implementing section D1.10.2 of the ARMv8 ARM,
and in particular table D1-7 ("Vector offsets from vector table base
address"), which describes which vector to use depending on the source
exception level and type (synchronous, IRQ, FIQ or SError).
