The atomic reset command uses mdelay so it should use
the standard reset time of 203ms otherwise the system
can get locked for many seconds.

Force power off should only be used in case the graceful
shutdown fails otherwise the esoc will be resetted even
when not needed.

Some options available for mdm9x45 esocs were missing from
the mdm9x55 setup hardware function. Add those to bring them
in sync. The way a power down is performed on mdm9x55 is also
changed to be similar to mdm9x45.

Power management irq wakeup mode is by default disabled.
Calling irq_set_irq_wake() on a disabled irq causes warning.
Remove irq_set_irq_wake() function from mdm_enable/disable_irqs
functions and set it once in probe.

Reset and power off timing is different. Hence need a
separate callback function.

In certain scenarios, modem shutdown requests are handled in
userspace. Enhance request engine of esoc driver to send
shutdown requests to userspace.
Also, during a shutdown, avoid setting status to 0, if line is
not a power source. There can be multiple mdms monitoring status
line. This can otherwise be misinterpreted as an unexpected reset
by other mdms.

During an unexpected reset or error fatal, update the
crash status to SSR. This is important for the drivers
listening at SSR related kernel notifier calls, where
crash status is also passed as a data payload.

Some of the external SoC are flash based and can boot independently.
Extend esoc driver to support such auto boot esocs.
This patch also adds support for primary esoc. Primary esoc are
esoc that control secondary esoc such as modems. Primary esoc have
control over reset/poweroff of secondary esoc. Secondary esoc don't
have control over reset/poweroff of primary esoc. In general modems
are considered as secondary esoc while apps processor is considered
as primary esoc.

Auto_boot esoc devices can boot and crash before
esoc driver comes up. But there is no way for the
user space code to know that it has crashed by looking
at status line alone. Hence, create a new ioctl entry
to export status of err_fatal line to user space.

SSR driver expects subsystem descriptor device type to be
struct platform_device, whereas esoc driver is passing a
struct device instead. This results in a NULL pointer crash
during platform_get_irq in subsystem_restart.c. Fix esoc
driver to pass platform_device.

ESOC IOCTL was designed to transfer data of type unsigned int, but
was pushing data of unsigned long type. Hence causing data corruption
in user space. Fix this by changing put user to use unsigned int.
