Ulf Hansson 18d200460c mmc: core: Respect MMC_CAP_NEED_RSP_BUSY for eMMC sleep command 
The busy timeout for the CMD5 to put the eMMC into sleep state, is specific
to the card. Potentially the timeout may exceed the host->max_busy_timeout.
If that becomes the case, mmc_sleep() converts from using an R1B response
to an R1 response, as to prevent the host from doing HW busy detection.

However, it has turned out that some hosts requires an R1B response no
matter what, so let's respect that via checking MMC_CAP_NEED_RSP_BUSY. Note
that, if the R1B gets enforced, the host becomes fully responsible of
managing the needed busy timeout, in one way or the other.
