Call flow control API when RNDIS packet filter control message is
received. This allows to call the registered flow control call back
from rndis clients supporting hw accelerated path.

This change starts using dl_max_packet_size value sent by host
as part of USB RNDIS init message communication. Using default
dl_max_packet_size value results into low throughput with more
data loss on host side as host side RNDIS can't support
de-aggregation (applicable for Linux Host RNDIS driver) or it
ignores received more data then host side RNDIS can handle. To
use fine tune dl_max_packet_size for better throughput, driver
selects minimum value between host supported dl_max_packet_size
and default size (i.e. 9216 bytes as RNDIS IN aggregation size).

Add pkt_alignment_factor rndis parameter. This
parameter along with max_pkt_per_xfer allow rndis
function driver to aggregate more than one IP packets
per transfer. This is done by calling newly added API
rndis_set_pkt_alignment_factor().

RNDIS protocol supports data aggregation on uplink and can help
reduce mips by reducing number of interrupts on device. Throughput
also improved by 20-30%. Aggregation is disabled by setting
aggregation packet size to 1. To help better UL throughput, set
as ul aggregation support to 3 rndis packets by default. It can be
configured via sysfs device attribute ul_max_pkt_per_xfer.

Some instances of USB controller get XO directly from the
pad and hence don't need a GCC clock to enable it. Allow
xo_clk to be optional if not specified in DT.
Speaking of optional clocks, remove the NULL checks and allow
clk_* APIs to get called unconditionally, since they already
handle NULL pointers. Finally remove the clk_put() call for
xo_clk since it is already devm managed.

Not all instances of the controller should be tied to the
USB power_supply. For example in cases of multiple instances,
we do not want all instances manipulating the SDP current
draw by setting the power_supply property, as there is only
usually only a single charger instance.
Replace power_supply lookup by "usb" name to a phandle lookup.
DT must specify a "qcom,usb-charger" property pointing to the
charger instance.

This change adds the driver for the USB controller on QTI MSM
devices. This is a snapshot of the driver from msm-4.19 as of
commit 104eef6e1fe8 ("platform: msm: Remove unused local count
variable").
In addition to the msm-4.19 version, this change includes several
fixups to address the following:
- Building dwc3-msm as a module. It is easiest to just merge
dbm.c into dwc3-msm.c.
- Coccinelle warnings, such as assigning 0/1 to a boolean and
missing newlines from log strings.
- Conversion of defunct msm_bus API to the interconnect bus
scaling API.
- Remove dead host controller handling as it depends on a
USB_BUS_DIED notification added to usbcore on downstream and
has not yet been mainlined on this kernel. We will either have
to bring in the atomic notifier or switch to listening to the
"ERROR=DEAD" uevent and take action from userspace.
- Remove extcon blocking notifier and MED_HIGH_CURRENT.
- Remove usage of PM_QOS_REQ_AFFINE_IRQ as PM QoS support for
specifying IRQ/CPU affinity is not supported upstream. Just
request a QoS level for all cores.
- Endpoints' ep_type EP_TYPE_GSI is now reflected in dep->gsi
- dwc3_stop_active_transfer() takes a dep directly and added
an additional parameter to skip IOC
- Remove RESTART_USB_SESSION notification as the usb_gadget_ops
restart_session is not supported in upstream
- dwc3_request->started replaced by DWC3_REQUEST_STATUS_STARTED
- Switch USB_DR_MODE_DRD enum back to USB_DR_MODE_OTG
- Directly write GUSB3PIPECTL_SUSPHY and DEVTEN registers instead
of needing APIs from core
- Remove clk_set_flags. These aren't needed now.
- Remove FLOAT charger handling.

Pure carveouts (i.e. memory that is completely unmanaged by the
kernel) do not have any initialization routines associated
with them. So, ignore them when checking if a region has already
been initialized by the reserved memory framework.

revisions > 3.30a, including dwc_usb31, do not support OTG.

need to restrict the operation to host-only or peripheral-only.
