Sometimes, the userspace driver has a need to disable some of the
power savings features in the kernel for a brief period. Add a
property to control nap and DCVS from the user space driver via
KGSL_IOCTL_SETPROPERTY.

The multimedia firmware on 8960 will always be
loaded into a fixed address, and all callers into
this firmware must be no more than 256M above the
start of this firmware.
This implies that the the mm ION heap and its associated heaps
(mm_fw and mfc) must also be created in a fixed place.
This version of the patch keeps the mm fw heap size
to 2M for compatibility with the current tip. This
will eventually be reduced to 1M.

To prevent I/O as soon as possible at card removal, a new
detect work is re-scheduled without a delay to let a rescan
remove the card device as soon a possible.
Additionally, MMC_CAP2_DETECT_ON_ERR can now be used to handle
"slowly" removed cards that a scheduled detect work did not
detect as removed. To prevent further I/O requests for these
lingering removed cards, check if card has been removed and then
schedule a detect work to properly remove it.

allows the Thermal Mitigation function in userspace to read and write
the current thermal mitigation level. An API is added to allow other
drivers (specifically the WLAN Driver) to register a notifier to be
invoked when the thermal mitigation level is changed.

In MSM architecture, the DBM, Device Bus Manager, is a HW module within
the USB3.0 core wrapper, implementing BAM interface support for USB3.0 IP.
The DBM HW unit requires for its operation a special transfer to be
started, with special TRBs structure. These usb requests will operate in
BAM2BAM mode.
This change adds to the dwc3-msm.c driver a support for queuing
a special transfers to endpoints which serve the DBM.
A function driver can now call to msm_ep_config(*ep) with some
endpoint which will serve the DBM. After this, the function
driver can queue a request to this endpoint as usual ep->queue(*ep,*req).
The function driver may need to add a few more parameters in req->udc_priv
field according to the bit mask fields defined in msm_hsudb.h file.

The req->udc_priv value is used to transfer parameters from a function
driver to a udc, for enabling sps/bam mode for MSM architecture.
This change moves the definitions of the bit fields inside the udc_priv to
msm_hsusb.h in order to avoid duplicate definitions in u_bam.c and
ci13xxx_udc.h. Also this will allow other function drivers and other udcs
to use this definitions, for example, debug class over dwc3 udc.
