An ASYNC interrupt is an indication by hardware that some
activity has happended on USB lines in LPM (low power mode),
and USB software should now bring it out of LPM.
Ideally, hardware should give one more interrupt after coming
out of LPM so that USB driver can process that accordingly.
But, sometimes this interrupt is not generated from h/w for
remote wakeup event in host mode. Hence, resume root hub on
receiving the ASYNC interrupt from hardware in Host mode.

Incorrect HMAC values are generated in following scenarios.
- In case of a single transfer with a packet shorter than the
block size, the HMAC generated is incorrect. This is due to
the "FIRST" bit in AUTH_CFG register not being set. When calling
HMAC_final for a transfer with a single packet (with no prior HMAC
updates), the "FIRST" and "LAST" bit in AUTH_CFG register needs to
be set. Currently FIRST bit is being cleared incorrectly for all
scenarios.
- In a scenario of a mac key input larger than block size, the key
needs to be hashed. The key hashing operation is crashing. This is
due to a NULL, unintialized pointer to the device handle. This is
fixed by intializing the pointer correctly. Further more, key size
is uninitialized, resulting in corruption of buffer.

Add runtime power management support in the driver which allows
putting the hardware in low power state, turning off LDOs
and releasing wakelock.
This LPM (aka low power state) support is currently added as part
of USB disconnect and wall-charger connect. LPM support would
later be extended to USB bus suspend as well. Also, support for PHY
retention mode and VDD minimization would be added later.
This commit also adds debugfs nodes that can used to simulate
cable connect and disconnects as A or B device. Following are
the nodes:
-->msm_dwc3/id : Boolean value
-->msm_dwc3/bsv : Boolean value
-->msm_dwc3/connect : can be set to enable/disable
User should first update id/bsv values before enabling 'connect'.
dwc3-msm device is parent of dwc3-core and its runtime PM is managed
by dwc3_otg driver which is responsible for the state transitions
based on notifications from DWC3 h/w or ext_xceiver (using PMIC) for
cable connect and disconnect. This change also allows dwc3 gadget and
host to acquire PM count for the case when dwc3-otg is not present -
