This reverts commit dbc6a7199e.
By moving the SS_PHY resume to before enabling clocks, this has
the added benefit of improving the QMP SS PHY LFPS handshake
response by about 1.5-2.0ms and thus decreases overall resume time.
However, for QSCRATCH-based PHYs care must be taken to ensure
that the USB3 controller master clock is turned on or else its
usb_phy_set_suspend() routine will encounter unclocked register access.
Two previous changes, commit e6572b0 "clock: msm: Add
gcc_usb30_master_clk to USB HS/SS PHY devices", and commit c7852f6c
"usb: phy-msm-ssusb: Add USB3 core clock" allow the QSCRATCH SS PHY
driver to now properly handle set_suspend() being called even when
the USB3 hasn't yet enabled its clocks. Thus we can now move the
usb_phy_set_suspend() back to its previous spot.

This PHY uses QSCRATCH registers which technically belong
in the USB3 controller IO space, therefore reads/writes to
them require the USB 3 master clock to be turned on. Since
the init() and set_suspend() routines could be executed while
the controller is in low power mode, explicity turn on the
clocks in order to guarantee clocked register access.

Current code put usb2 phy into autosuspend mode and poll for IN_L2
pwr_event to be set while putting device into LPM on receiving SUSPEND
event. There is a possible race that arises when gadget events are
processed before the resume routine has disabled the USB2 PHY autosuspend.
Some of the gadget events issue endpoint commands which may time out since
the PHY is still autosuspended. Fix this issue by using available check
where it calls dwc3_gadget_usb2_phy_suspend() API to disable usb2 phy
autosuspend, and ignore hsphy_auto_suspend_disable platform specific
variable.
Also add error messages where this failure case is checked.

This change adds a few more APIs to the phy_ops structure:
advertise_quirks - an API for setting the phy quirks
suspend - an API for the implementation of
phy suspend sequence
resume - an API for implementation of phy resume sequence

Crashes are observed during bootup due to unclocked access of Panic

During ramdump collection, the modem subsystem needs the MBA to be
loaded again. The allocation of memory done during that time is not
currently being freed and as a result, the common CMA area is getting
filled up.
Explicitly free the allocation area before bringing down the subsystem.

Currently, OCP hold is set to zero by default which is
preventing the PA from holding the shutdown state.
Set this bit to enable OCP hold by default. Once hold is set
PA would shut down immediately during overcurrent and hold
that state unless SPKR_PA_EN bit is toggled.

Callback notifications lock the channel status to prevent clients from
unregistering their callback function and other information while it is
in use during a notification. However, in some scenarios, clients use
the notification context to call back into bam_dmux which can result in
lock recursion.
Avoid the issue by caching the callback information, and then unlocking
the channel state before invoking the client's callback.
