Currently in f_cdev driver, we are not handling the TIOCM_CTS
signal generared by SIO_IOCTL_INBOUND_FLOW IOCTL. Hence we
are not able to send BRK signal to the host and it keeps
sending data leading to data loss.
Fix this by handling TIOCM_CTS in the driver.

On some targets, f_serial switches transport path from
char_bridge to TTY in DUN+SoftAP scenario. As a part of that,
we call usb_cser_disconnect but notify_modem callback is still
marked as usb_cser_notify_modem. Then on getting a SETUP req
from host PC, usb_cser_notify_modem is called which can lead
to NULL pointer dereference because port_usb is NULL.
Fix this by marking notify_modem callback as NULL on
usb_cser_disconnect.

When the host PC sends a DTR high during DUN call,
it expects to get a DSR signal from the modem in reply.
Add necessary support for that.

If CONFIG_QCOM_COMMAND_DB=n the following compilation errors will be
seen. Fix this by including the appropriate linux headers.
./include/soc/qcom/cmd-db.h: In function ‘cmd_db_read_aux_data’:
./include/soc/qcom/cmd-db.h: error: implicit declaration of function ‘ERR_PTR’;

For synchronous messages sent from the agent to platform,
agent waits for response for 30 milli seconds (max_rx_timeout)
before timing out if response gets delayed from platform.
Increase the timeout value to 1 second to minimize message
send failures in case of delays.

Record cycle count and kernel time in ns while entering suspend
and while resuming. This will help in matching up the kernel time
with external subsystems and in recording suspend time in cycles.

Print epoch values when the device is enter and exit out of suspend
and resume. These epoch values are useful to know how long the device
is in suspend state. These values can be used to synchronize various
subsystem timestamps and have an unique timestamp to correlate
between various subsystems.

There might be spurious HS PHY IRQ after USB bus has gone into
hibernation which leads to dwc3_msm_resume and in_lpm flag
getting cleared. Next when the restore from hibernation happens,
dwc3_msm_resume becomes a no-op but in reality, the HW resources
are all turned off. This leads to an unclocked access from
xhci_resume.
Fix this by disabling PHY wakeup IRQs on hibernation/pm_suspend
for automotive targets.

Cpu possible sibling cpu mask is only used by WALT for its cluster
population. And WALT is directly getting the cpu possible sibling mask.
So remove this unused cpu mask support by reverting commit:
'6df025a02c49f65("topology: Add snapshot of possible sibling
cpu mask changes")'.
