abd7cedb19 cmd: usb: ignore blk, emulation devices in usb tree/info display
Usb tree/info commands iterate over all usb uclass devices recursively.
Blk uclass devices based on struct blk_desc are created for mass storage
device, treating them as usb uclass devices based on struct usb_device
and referencing usb config interface descriptors cause crash.
To fix, ignore blk and usb_emul uclass devices in usb_show_info
and usb_tree_graph. Also avoid addition of preamble for blk uclass
child devices, otherwise tree dump gets messed up.

Instead of having separate code in the 'usb' command, adjust it to use

b984700ca4 usb: storage: Show number of storage devices detected for DM_USB
By enabling DM_USB information about number of storage devices
was lost.
Get this information back simply by printing number of devices detected
via BLK uclass.

For example:
scanning bus 0 for devices... 7 USB Device(s) found
       scanning usb for storage devices... 3 Storage Device(s) found
       scanning usb for ethernet devices... 0 Ethernet Device(s) found

e6e188f562 usb: dm: Make "usb info" use usb_for_each_root_dev()
The old dm "usb info" implementation has several issues:

1) NULL pointer deref when a bus has no children
2) Not showing usb devices on busses without an emulated root-hub (otg host)
3) Attempting to show devices on inactive busses
4) "usb info" Would cause some hosts to get re-probed something which only
   "usb reset" should do

TL;DR: proper iterating over usb bus root devs is hard, use the helper
for it.

2138fd6d5d usb: dm: Add a usb_for_each_root_dev() helper function
Iterating over usb-root devs and doing something for all of them is
a bit tricky with dm, factor out the proven usb_show_tree() for this
into a helper function.

7839f5f809 cmd: usb: check if_type before using this device
For legacy usb storage driver, USB_MAX_STOR_DEV is defined as 7.
If we only have one usb disk on board, `usb dev 0` is ok.
But if `usb dev 1`, still ok, then `usb read xxx` will trigger
system fault and reboot.

So check if_type before using this device.

192eab9357 dm: usb: Do not reprobe usb hosts on "usb tree" command
Some usb hosts may have failed to probe on "usb start", i.e. an otg
host without an otg-host cable plugged in.

"usb tree" would cause the probe method of these hosts to get called
again, something which should only happen on "usb reset".

This commit fixes this.

9a80e71435 usb: kbd: Do not deregister usbkbd twice when using dm
The dm usb_kbd_remove function() will deregister the usb keyboard for
us on a "usb reset" / "usb stop" so there is no need to manually call
usb_kbd_deregister() in the dm case.

This commit removes usb_kbd_deregister() in the dm case fixing the
following "usb reset" errors:

usb_kbd_remove: warning, ret=-6
device_remove: Device 'usb_kbd' failed to remove, but children are gone

2a981dc2c6 dm: block: Adjust device calls to go through helpers function
To ease conversion to driver model, add helper functions which deal with
calling each block device method. With driver model we can reimplement these
functions with the same arguments.

Use inline functions to avoid increasing code size on some boards.
