[Patrick Rudolph (Code Review)]

Hello Alexander Couzens, Patrick Rudolph, Richard Hughes, build bot (Jenkins), Patrick Georgi, Martin Roth,

I'd like you to reexamine a change. Please visit

to look at the new patch set (#6).

Change subject: lenovo/*: Fix DRAM init when WWAN card is present

lenovo/*: Fix DRAM init when WWAN card is present

The WWAN slot isn't powered by default. In case a WWAN card, that
support SMBUS is installed, it pulls the lines low.

Enable power on WWAN on those devices that connect SMBUS to the
WWAN slot.

Resolves an issue where DRAM init fails as no EEPROM could be
found on the bus.

Tested on X220: Boots with WWAN card inserted.
