toshiba_acpi: Add extra check to backlight code

Some Toshiba models (most notably Qosmios) come with an
incomplete backlight method where the AML code doesn't
check for write or read commands and always returns
HCI_SUCCESS and the actual brightness (and in some
cases the max brightness), thus allowing the backlight

https://forums.lenovo.com/t5/Linux-Discussion/Yoga-2-13-not-Pro-Linux-Warning/m-p/1517612

Testing has shown that the firmware rfkill settings are persistent over
reboots. So blacklisting the driver is not good enough, if the wifi is blocked
at the firmware level the wifi needs to be explictly unblocked through the
ideapad-laptop interface.

And at least on the Lenovo Yoga 2 13 the VPCCMD_RF register which on devices
with hardware kill switch reports the hardware switch state, needs to be
explictly set to 1 (radio enabled / not blocked).

So this patch does 3 things to get proper rfkill handling on these models:

1) Instead of blacklisting the rfkill functionality, which means that people
with a firmware blocked wifi get stuck in that situation, ignore the value
reported by the not present hardware rfkill switch, as this is what is causing
ideapad-laptop to wrongly report all radios as hardware blocks. But do register
the rfkill interfaces so that the user can soft [un]block them.

2) On models without a hardware rfkill switch, explictly set VPCCMD_RF to 1

3) Drop the " 11" postfix from the dmi match string, as the entire Yoga 2
series is affected.
