ASoC: msm: Reset the stream open flag after CMD_CLOSE is sent to DSP

In case of gapless playback, driver does not wait for EOS. CMD_CLOSE
for stream one or two can be called from compress driver free before
EOS ACK for stream one is received. This can result in CMD_CLOSE to
be sent for already closed stream. Reset the stream open flag after
CMD_CLOSE is sent to DSP to prevent multiple CMD_CLOSE on same
stream.

mmc: sdhci: add asynchronous interrupt support for sdio card

Some controllers can gate the clock to save power
even for SDIO cards. In such cases, an asynchronous
interrupt mechanism is used to receive interrupts
even when clocks are off.

This patch wakes up the sdio thread if interrupts
were received when clocks were off.

This patch adds wakeup event capability for sdio cards.
When a wakeup event is received during suspend, a reference

It is expected that the function driver would act on the
wakeup event within this time-period.
