[Bug 30987] sdhci driver is _very_ verbose

[Martijn van de Streek]

Public bug reported:

Affects: linux-source-2.6.15 (Ubuntu)
       Severity: Normal
       Priority: (none set)
         Status: Unconfirmed

Description:
Since the latest kernel update, sdhci works. But WHEN it's doing things,
it spams my dmesg with this message:

[4297496.104000] mmc2: DMA end

Thousands of times.

As this is obviously debug info, I think it should be removed.
