Ulf Hansson 1760fdb6fe mmc: core: Restore (almost) the busy polling for MMC_SEND_OP_COND ... Commit 76bfc7ccc2 ("mmc: core: adjust polling interval for CMD1"), significantly decreased the polling period from ~10-12ms into just a couple of us. The purpose was to decrease the total time spent in the busy polling loop, but unfortunate it has lead to problems, that causes eMMC cards to never gets out busy and thus fails to be initialized. To fix the problem, but also to try to keep some of the new improved behaviour, let's start by using a polling period of 1-2ms, which then increases for each loop, according to common polling loop in __mmc_poll_for_busy().
