mmc: core: Fix busy polling for MMC_SEND_OP_COND again
commite949dee362
upstream. It turned out that polling period for MMC_SEND_OP_COND, that currently is set to 1ms, still isn't sufficient. In particular a Micron eMMC on a Beaglebone platform, is reported to sometimes fail to initialize. Additional test, shows that extending the period to 4ms is working fine, so let's make that change.
