yes i'm hopeful that someone from Broadcom knows more about the capabilities.
This patch only copies them from the other driver, because i don't want to
introduce new issues.

Unfortunately the BCM2835 datasheet refers only to a non-public Asaran document
( SD3.0_Host_AHB_eMMC4.4_Usersguide_ver5.9_jan11_10.pdf ).

Best regards
Stefan
