dw_mmc: reduce max polling wait to one second
Under high memory pressure, SDIO interrupts are missed triggering card
resets and link monitor failures. This is combated by reducing the
maximum time between polling loops to one second. This commit also
fixes the increasing backoff time between loops. The wait time is
checked after the calculation to verify it is not longer than 1 second.
BUG=chromium:468342
TEST=Multiple runs of the loaded network test script that maintains high
memory pressure while performing curl requests - watched for link
monitor failures and card resets.
