Log:
OLPC XO-1.75 A2 A3 - Remove delay on access to external SD now that
discharge switches are in place.  " t( dir ext:\ )t " shows 562ms before
this patch, and 94ms after this patch.  Even more time is saved when a
directory is accessed.  Has no effect on internal SD.  #10512.

Breaks A1 external SD for some cards, but we are no longer building for
A1 and a workaround can be used prior to access: " dev /sd d# 250 to
power-off-time "
