[PATCH] Fix IGEPv2 second MMC channel power supply

[Marc Zyngier]

Commit 72f381ba056 removed an unused regulator entry, but left
the second MMC channel (used by the Libertas WLAN mudule) without
link to power regulator. This causes the SDIO module to fail being
detected.

This patch adds a second supply to the existing MMC1 regulator,
and let MMC2 hang off it. With that patch, the second channel is
properly detected.

Tested on an IGEPv2 Rev-B.

Note that this doesn't fix WLAN itself on 2.6.37-rc1...
