thinkpad-acpi: fix incorrect use of TPACPI_BRGHT_MODE_ECNVRAM
HBRV-based default selection of backlight control strategy didn't work
well, at least the X41 defines it but doesn't use it and I don't think
it will stop there.
Switch to a white/blacklist. All models that have HBRV defined have
been included in the list, and initially all ATI GPUs will get
ECNVRAM, and the Intel GPUs will get UCMS_STEP.
Symptoms of incorrect backlight mode selection are:
1. Non-working backlight control through sysfs;
2. Backlight gets reset to the lowest level at every shutdown, reboot
and when thinkpad-acpi gets unloaded;
This fixes a regression in 2.6.30, bugzilla #13826
