Comment(by martin.langhoff):

 This grep shows the relevant symbols in our current kernel

 {{{
 git grep -C5
 '\(MMC_CAP_NONREMOVABLE\|mmc_assume_removable\|MMC_UNSAFE_RESUME\)'
 }}}

 My analysis is that we should remove MMC_UNSAFE_RESUME, and somewhere in
 the platform files tell the MMC layer that our eMMC device and our
 internal SD slot have MMC_CAP_NONREMOVABLE.

 The grep pattern turns up a couple of boards that do exactly that.
 Unfortunately, we don't seem to be setting up a sh_mobile_sdhi_info
 struct, to we got to rig that up.
