thinkpad-acpi: fix default brightness_mode for R50e/R51
According to a report, the R50e wants EC-based brightness control,
even if it uses an Intel GPU. The current driver default was reported
to not work at all.
This bug can be worked around by the "brightness_mode=3" module
parameter.
Change the default of the R50e and R51 2xxx models (which use the same
EC firmware, 1V) to TPACPI_BRGHT_Q_EC, but keep TPACPI_BRGHT_Q_ASK set
for now, as I'd like to get more reports.
This fixes a regression caused by commit
59fe4fe34d7afdf63208124f313be9056feaa2f4,
"thinkpad-acpi: fix incorrect use of TPACPI_BRGHT_MODE_ECNVRAM"
Kernel 2.6.31 also needs this fix.
