mmc: core: Fix busy polling for MMC_SEND_OP_COND again
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.
