Add support for scanning USB storage devices with driver model. This mostly
involves adding a USB device ID for storage devices.

The usb_stor_scan() function is quite long, so split out the code that scans
each device into its own function. Also, rather than setting up the block
device list once at the start, set it up as each device is scanned. This
makes it possible to use this code from driver model.

This function now calls usb_setup_device() to set up the device and
usb_hub_probe() to check if it is a hub. The XHCI special case is now a
parameter to usb_setup_device(). The latter will be used by the USB uclass
when it is added, since it does not rely on any CONFIGs or legacy data
structures.

usb_new_device() is far too long and does far too much. As a first step, move
the code that does initial setup and reads a descriptor into its own function
called usb_setup_descriptor().
For XHCI the init order is different - we set up the device but don't
actually read the descriptor until after we set an address. Support this
option as a parameter to usb_setup_descriptor().
Avoid changing this torturous code more than necessary to make it easy to
review.

Adjust this command to work with the new driver model uclass. It needs to
iterate through multiple independent controllers to find hubs, and work

Convert this driver over to use driver model. Since all x86 platforms use
it, move x86 to use driver model for SPI and SPI flash. Adjust all dependent
code and remove the old x86 spi_init() function.
Note that this does not make full use of the new PCI uclass as yet. We still
scan the bus looking for the device. It should move to finding its details
in the device tree.

Sometimes, for example if the display is mounted in portrait mode or even if it
is mounted landscape but rotated by 180 degrees, we need to rotate our content
of the display respectively the framebuffer, so that user can read the messages
which are printed out.
For this we introduce the feature called "CONFIG_LCD_ROTATION", this may be
defined in the board-configuration if needed. After this the lcd_console will
be initialized with a given rotation from "vl_rot" out of "vidinfo_t" which is
provided by the board specific code.
If CONFIG_LCD_ROTATION is not defined, the console will be initialized with
0 degrees rotation.

Since we support multiple dwc3 controllers to be existent at the same
time, in order to handle the interrupts of a particular dwc3 controller
usb_gadget_handle_interrutps should take controller index as an
argument.
Hence the API of usb_gadget_handle_interrupts is modified to take
controller index as an argument and made the corresponding changes to all
the usb_gadget_handle_interrupts calls.

When fetching the first descriptor from a new device, only validate that
we received at least 8 bytes, not that we received the entire descriptor.
The reasoning is:
- The code only uses fields in the first 8 bytes, so that's all we need
to have fetched at this stage.
- The smallest maxpacket size is 8 bytes. Before we know the actual
maxpacket the device uses, the USB controller may only accept a single
packet (see the DWC2 note in the comment added in the commit).
Consequently we are only guaranteed to receive 1 packet (at least 8
bytes) even in a non-error case.

The ARM reference designs all use a special flash image format
that stores a footer (two versions exist) at the end of the last
erase block of the image in flash memory.
Version one of the footer is indicated by the magic number
0xA0FFFF9F at 12 bytes before the end of the flash block and
version two is indicated by the magic number 0x464F4F54 0x464C5348
(ASCII for "FLSHFOOT") in the very last 8 bytes of the erase block.
This command driver implements support for both versions of the
AFS images (the name comes from the Linux driver in drivers/mtd/afs.c)
and makes it possible to list images and load an image by name into
the memory with these commands:
afs - lists flash contents
afs load <image> - loads image to address indicated in the image
afs load <image> <addres> - loads image to a specified address
This image scheme is used on the ARM Integrator family, ARM
Versatile family, ARM RealView family (not yet supported in U-Boot)
and ARM Versatile Express family up to and including the new
Juno board for 64 bit development.
