Currently the external modem's boot fail configurations,
boot_fail_action and n_pon_tries, are set via module parameters.
Convert it to an IOCTL so that a registered user-space
application has control over the configurations.

The definitions under 'enum esoc_client_hook_prio' and 'struct
esoc_link_data' are used only by kernel drivers, and not needed
by user-space. Hence, move the definitions from uapi header file
(uapi/linux/esoc_ctrl.h) to kernel internal header file
(linux/esoc_client.h).

Due to recent hardware limitations, the requirement is to do
the warm reset of the modem twice. Once for collecting the
dumps and the other for transferring the firmware images.
If during the process, the driver receives a failed notification,
then power-off the modem. Hence, add code to support these
functionalities.

There is no way for the mdm-helper to know that the
modem has crashed to take necessary action.
Hence, added the support that sends a notification to the
user-space, through IOCTL, as and when the modem sends an
error fatal interrupt to the driver.

Some subsystems/drivers require notifications from the esoc
driver as soon as the it powers on/off the modem.
For this, the clients cannot directly depend on the
SSR notifications.
Hence, adding support such that the clients who are
interested in listening to such events can register
themselves. Moreover, the order in which these notifications
are sent to the clients can be prioritized statically.
Also, a flexibilty is added such that the user-space
can get information, such as link-id, from the interested
client.

This is a snapshot of the esoc driver as of msm-4.4 commit <9d5748a>
(Merge "ARM: dts: msm: disable wdog wakeup on msm8996 vplatform").
The change also removes the support for older modems which are no
longer used.
