This fixes a bug introduced in commit 3f4e52fc9d81 https://source.denx.de/u-boot/u-boot/-/commit/3f4e52fc9d81e95ee90f6be7b05ca6... and it is incorrect. It caused the mmc initialization to take 4 seconds (previously it was <0.1s).
The code in Linux also uses &&, and the comment says: If the host doesn't support HW polling via the ->card_busy() ops and when it's not allowed to poll by using CMD13, then we need to rely on waiting the stated timeout to be sufficient.

Peng, could we get this merged ASAP? :)
