mmc: Split device init to decouple OCR-polling delay
Most of time that MMC driver spends on initializing a device is polling
OCR (operation conditions register). To decouple this polling loop,
device init is split into two parts: The first part fires the OCR query
command, and the second part polls the result. So the caller is now no
longer bound to the OCR-polling delay; he may fire the query, go
somewhere and then come back later for the result.
To use this, call mmc_set_preinit() on any device which needs this.

usb: hub: Parallelize power-cycling of root-hub ports
Untill now we power-cycle (aka: disable power on a port

Delay of 20ms for Port-power to change multiplies with
number of ports in this case.
So better we parallelize this process:
disable power on all ports, wait for port-power to stabilize
and then re-enable the power subsequently.
Patch b6d7852c increases timeout for enumeration, taking
worst case to be 10 sec.
get_timer() api returns timestamp in milliseconds, which is
what we are checking in the do-while() loop in usb_hub_configure()
(get_timer(start) < CONFIG_SYS_HZ * 10).
This should give us a required check for 10 seconds, and thereby
we don't need to add additional mdelay of 100 microseconds in
each cycle.
