[U-Boot] [PATCH] mmc: sdhci: increase default timeout and make it configurable

[Masahiro Yamada]

I found the current timeout is too short for some devices to execute
erase command.  Nor can we override CONFIG_SDHCI_CMD_DEFAULT_TIMEOUT
from a board config.

Increase the default timeout and surround the define with "ifndef"
to allow to override it in case the default value is not a good fit.
