The si32260 chip may enter a state of thermal alarm to avoid
overheating. This disables the channel.
This commit allows automatic restoring of the channel after a certain
timeout (poll_chan_linefeed, by default 30 seconds).
Adds a per-channel counter ("overheats") in
/proc/xpp/XBUS-<n>/XPD-<m>0/fxs_info to count such events.

The xpp drivers were originally developed seperately and thus had their
own version number. For quite some time they no longer have this version
number and report 'Revision: Unknown'.
Get rid of this mechanism.

Generation of metering tone (a feture normally disabled at build time)
is not yet implemented on the new FXS type 6 module.

The new FXS chip supports two ports for each chip and hence we once
again need to look at hardware differently.
Struct unit_description includes information about all chips/port in a
specific module.

Currently we only have REG (register) commands. Refactor it to allow

A new SysFS interface for FXS modules (XPDs):
* In /sys/bus/xpds/devices/<ll>:<m>:<n>/fxs_ring_registers
* Reading show current register values for NEON/TRAPEZ/NORMAL
* Modify the table via writing: "<column> <reg> <byte> [<byte>]"
* Example:
echo "NEON 0x33 0x12" > \
'/sys/bus/xpds/devices/00:0:0/fxs_ring_registers'

xpp: refactor the FXS module ring settings into separate data structure:
* Update High VBAT initialization in init_card_1_30:
- Take the value used in set_vm_led_mode() (0x34)
- Now we don't need to set it over and over again in set_vm_led_mode()
* Create a unified ring_parameters[] array for all ring registers:
- Columns for 3 ring types (NEON, TRAPEZ, NORMAL)
- Used by new send_ring_parameters() function
* Now the set_vm_led_mode() simply calls send_ring_parameters()
* This cleanup would allow us to change ring parameters at runtime (by
updating the values in these tables).

Don't use create_proc_read_entry() as that is deprecated, but rather use
proc_create_data() and seq_file instead.
This is needed to compile against Linux 3.10.

* This is a minimal convertion -- everything compiles and looks OK.
* We print a warning for spans registering without a spantype.
* Low-level drivers may later want (but not required)
to fold their internal representations to this canonical
representation -- it will save code and make it more readable.

* Adds a new parameter, 'lower_ringing_noise', to module xpd_fxs.
* Makes the "power-down" behaviour that was added
in upstream svn r10478, switchable in runtime.
* By default (false), makes the vbat_h behave like it did
before the power-down change.
- I.e: vbat_h is held throughout the ringing period (during
both ring-up/ring-down)
- So this patch revert part of r10478
* When switched to true, activate the "power-down" behaviour.
- I.e: vbat_h follows the ring-up/ring-down.
- This behaviour lowers the noise caused by group ringing of
FXS channels in the same unit, but causes problems with CallerID.

* Now every linefeed control command which is not RING'ing
powers-down the SLIC. This reduce audible noise when
several channels are ringing.
* Simplify code by removing redundant calls to do_chan_power()
before linefeed_control()
* Manage vbat_h state so we skip do_chan_power() calls when
there isn't a state change
* Export vbat_h state to /proc/.../fxs_info

This patch removes support for kernel versions < 2.6.18, as those are
not actively supported in any major Linux distribution (except RHEL4,
which is in the "extended" support level of the product life cycle).
This removes much of the more #ifdef-rich parts of the code.

* Bug sympthoms: wrong FSK VMWI sent few seconds after
offhook. That was caused because the driver kept
polling the (physically unconnected) digital inputs.
[note: a workaround for drivers without this patch
is to zero the 'xpd_fxs.poll_digital_inputs' parameter.]
* Also, the digital_inputs/digital_output masks were
calculate using a different condition.
* Now we determine number of channels, digital inputs and
digital outputs in a single place and use this info
later to calculate the correct masks.
* We poll only if there are digital_inputs
* We added a sanity check in process_digital_inputs, so
we get a notice if it's called on an xpd without digital
inputs (e.g: hypothetic firmware bug).
