Add support for handle 0x0143 (Vaio SA/SB/SC, CA/CB) and rework the code
to be hable to support different handles for the keyboard backlight
function.

A few models offer the chance to set whether to resume from S3 and/or S4
when opening the lid.
[malattia@linux.it: create three sysfs files for S3/4/5 rather than
using a single one accepting a bitmask. Support S5 since the DSDT
exports it. Use a struct to hold all the related values, caching of the
current status value rather than re-reading all the time in the sysfs
show function.]

Loop through the list of SNC handles and run the proper initialization
function for each of the known handles. Also return void in function
where we are not checking the return value anyway.
For notifications we also know which handle is linked to the event and
the code becomes simpler to read with a switch rather than using
convoluted ifs.
[malattia@linux.it: Code reworked to merge the initialization code
improvements and the notify callback changes. Modified the code paths to
allow easier error exit paths. Also fixed some missing break statements
and spelling mistakes.]

All calls into the SNC device methods have zero or one arguments and
return an integer or a buffer (some functions go as far as returning an
integer _or_ a buffer depending on the input parameter...).
This allows simplifying a couple of code paths and prepares the field
for other users of functions returning buffers.

The SNC device on recent Vaio laptops also stores the soft status and

Some Toshiba laptops have the transflective LCD and toshset
can control its backlight state. I brought this feature to the
mainline. To support transflective LCD, it's implemented by
adding an extra level to the backlight and having 0 change to
transflective mode. It was tested on a Toshiba Portege R500.

Currently the backlight device is registered unconditionally, but many
(probably most) Toshibas either don't support HCI_LCD_BRIGHTNESS or only
support reading from it. This patch adds a test of HCI_LCD_BRIGHTNESS
during initialization and only registers the backlight device if this
interface supports both reads and writes.

The tp_features.bright_acpimode will not be set correctly for brightness

The XO-1 rfkill driver should only send EC commands when changing
between blocked/unblocked state.
The rfkill switch is asked to be unblocked on every resume (even when
the card was never blocked before) and sending a EC_WLAN_LEAVE_RESET
command here upsets the resume sequence of the libertas driver. Adding
the check to avoid the spurious EC_WLAN_LEAVE_RESET fixes the wifi resume
behaviour.
The rfkill state is maintained by the hardware over suspend/resume
so no extra consideration is needed here.

As long as there is no other non-const variable marked __initdata in the
same compilation unit it doesn't hurt. If there were one however
compilation would fail with
error: $variablename causes a section type conflict
because a section containing const variables is marked read only and so
cannot contain non-const variables.

Whilst most monitors do wire up the HPD presence pin, it seems quite a
few KVM do not. Therefore if we simply rely on the HPD pin being
asserted to indicate a connected monitor we fail miserable, so fall back
to performing a DCC query for the EDID.

Data valid gets cleared by reading the ISR (status register) and NOT from
reading ODATA (data register). A new data word can become available between
checking ISR and reading ODATA, causing us to reuse the same data word next
time atmel_trng_read() gets called, if that happens before the following
data word is ready.
With this fixed, rngtest no longer complains of 'Continous run' errors.
