[PATCH] Some SD cards require more retries in mmc_init

[Paul Fertser]

This patch effectively doubles maximum time allowed for retries performed by
mmc_init. Also, the delay was shortened to lower the average time needed to
init a card. Without it, i was unable to boot from Transcend TS8GUSDHC4
(appending rootdelay=1 was necessary as well).
