Introduce response and request structs for receiving information
regarding FW/SOC capability from DM. The received capability can
further be used to call certain API's based on the feature supoorted
by the DM firmware.

When FIT image with multiple dtbs are involved for R5 boot process,
R5 SPL starts off with the first instance of dtb to probe the
eeprom, then once we have identified the type of board, invocation
of setup_multi_dtb_fit will replace the gd->fdt_blob with the proper
board dtb match. However, when we do this, two things happen:

a) Prior to the invocation of setup_multi_dtb_fit, as part of the eeprom
   discovery process, i2c controller device is already probed and marked
   as exclusive with the match of the very first tisci match (from the
   original boot dtb). This list is stored in the info->dev_list of the
   first probe.
b) When the second dtb is loaded, tisci is probed again (since this is a
   new node) and the new info->dev_list is empty.

At this stage, the exclusive devices such as i2c instances used to
probe the board information is left in the old info->dev_list that is
no longer used actively by the system using the replaced dtb.

As a result of this, the cleanup we intend to do with
ti_sci_cmd_release_exclusive_devices is no longer complete and
leaves the instances such as i2c for eeprom marked used as we scan just
the new info->dev_list.

This creates a problem when Device Manager(DM) firmware starts up later
on in the boot process and identifies that this instance of i2c is
already marked active, so it assumes this can no longer be controlled
by software and is marked internally as reserved and HLOS can no
longer control these instances. This defeated the purpose of
ti_sci_cmd_release_exclusive_devices.

NOTE: This scheme works just fine if the FIT has just a single dtb as
the info->dev_list is upto date.

To fix this, let us make ti_sci_cmd_release_exclusive_devices scan the
all registrations of tisci instances and cleanup all exclusive devices
that have ever been registered.

As part of this, change the prototype of release_exclusive_devices to
drop the handle since that has no further meaning now.

Though this issue was identified on AM64-sk, this can be present in
other builds which use multi-fit-dtb for R5 SPL startup.

The common TI SCI header file uses some macros from err.h and these
get exercised when CONFIG_TI_SCI_PROTOCOL is not defined. Include
the linux/err.h header file in this header file directly rather
than relying on source files to include it to eliminate any
potential build errors.

While at this, reorder the existing header file include to the
beginning of the file.

Any host while requesting for a device can request for its exclusive
access. If an exclusive permission is obtained then it is the host's
responsibility to release the device before the software entity on
the host completes its execution. Else any other host's request for
the device will be nacked. So add a command that releases all the
exclusive devices that is acquired by the current host. This should
be used with utmost care and can be called only at the end of the
execution.

Add and expose a new processor shutdown API that wraps the two TISCI
messages involved in initiating a core shutdown. The API will first
queue a message to have the DMSC wait for a certain processor boot
status to happen followed by a message to trigger the actual shutdown-
with both messages being sent without waiting or requesting for a
response. Note that the processor shutdown API call will need to be
followed up by user software placing the respective core into either
WFE or WFI mode.
