Currently USB driver is not failing probe if USB core-clk-rate property
is not exist. This leads to USB enumeration failures across connect/
disconnect. Hence make core-clk-rate property mandatory and if in case
not defined, fail the probe. Also Fail probe if extcon property not
defined in case of OTG mode.
Also return error if dwc3_core_pre_init() fails during dwc3-msm_resume()
due to phy init fails and don't go ahead with setting up event buffers
as event buffers allocation is done.

When host RNDIS sends reset message it skips response available
notification and directly sends get encap response. This causes
notify count to become > 1. As a result when notify completion happens
driver is queuing another notify response available when there is
no legitimate response to send from device side. Hence reset notify
count back to 0 after the completion of notify response, so that
next notification will only be sent when there is a send encap
command sent by host.

If PMIC provides boost power for VBUS in host mode, it may
need to know the amount of current of an attached device
in order to optimize for overall power consumption. We can
pass the bMaxPower obtained from a device's configuration
descriptor when it is attached. This only affects devices
(including hubs) directly attached to the root port, as
any device downstream of a hub will either consume part of
the hub's budget or has external power.

Currently, in the power supply notifier callback, GEN3 FG driver
calls pm_stay_awake() which increases the wake source count on
its device before it schedules status_change_work. In case, if
status_change_work is already pending, then pm_stay_awake() will
not have a balanced pm_relax() call as the work will not get
scheduled again if it's pending already. Fix this by scheduling
status_change_work and hence call pm_stay_awake() only if it is
not pending.

Current code is resizing each USB IN endpoint's TXFIFO to 1KB if it is
not USB GSI endpoint or bursting is not enable. In some high throughput
test case where there is contention in terms of accessing DDR memory
through SNOC between USB3 and other peripheral PCIE, there are many
underrun errors (i.e. Bad Data Length/Bad CRC) observed. These errors
results into retransmision of USB packets and sometime dropping packets
causing diffrent kind of data stalls. Hence fix this issue by increasing
TXFIFO size as 3KB with endless USB IN endpoint (i.e. USB BAM2BAM
endpoint) which helps to successfully retransmit packets.

There is a chance that error might occur in connect_work before
endless request is queued to USB controller and bails out. In this case,
DBM endpoint will not be disabled and results in setendpoint config
command timeouts after next connect and could cause usb endpoint enable
fails. Fix this by disabling DBM endpoint corresponding to USB endpoint
in msm_ep_unconfig() if there are no requests queued to USB endpoint.
