Microblaze uses gpio which is connected to the system reset.
Currently gpio subsystem wasn't used for it.

Add gpio driver and change Microblaze reset logic to be done
via gpio subsystem.

There are various configurations which Microblaze can have
that's why gpio_alloc/gpio_alloc_dual(for dual channel)
function has been introduced and gpio can be allocated
dynamically.

Adding several gpios IP is also possible and supported.

For listing gpio configuration please use "gpio status" command

This patch also remove one compilation warning:

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.

This can save significant amounts of time on boot (e.g. 200ms) by
hiding the MMC init time behind other init.

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.

The Hydra and Superhydra (P3041DS, P5020DS, and P5040DS) boards have a
second USB port that can be configured in either host, peripheral (aka
device), or OTG (on-the-go) mode.  When configured in host mode, if
the port is connected to another USB host, damage to the board can
occur.

To avoid this, we change the default setting to peripheral mode.  Ideally,
we'd set it to OTG mode, but currently there is no OTG support for
these boards.

Setting the hwconfig variable will also update the device tree, and so
Linux will configure the port for peripheral mode as well.

When P1021RDB-PC reboot system, the board will hung at uboot DDR
configuration. For P1021RDB-PC DDR reset pin is multiplex with
QE, so uboot will reserve this pin for QE and skip DDR reset.
Other platforms without QE will do this reset. This patch adds
a slight code to reset DDR chip by QE CE_PB8 pin for NAND and
NOR FLASH boot. For booting from SPI FALSH and SD card, it
seems possible to use the rom on chip to write to the GPIO
pins before configuring the DDR.
