As explained in commit 4af2a33ee5 ("cmd: gpio: Make `gpio input`
return pin value again") the `gpio input` is used in scripts to obtain
the value of a pin, despite the fact that CMD_RET_FAILURE is
indistinguishable from a valid pin value.
To be able to detect failures and properly use the value of a GPIO in
scripts we introduce the `gpio read` command that sets the variable
`name` to the value of the pin. Return code of the `gpio read` command
can be used to check for CMD_RET_SUCCESS or CMD_RET_FAILURE.
CONFIG_CMD_GPIO_READ is used to enable the `gpio read` command.

Attaching a UBI partition may take a while, since scanning the memory is
required.
It thus makes sense to avoid a detach/scan/attach cycle when the right
partition is already attached, and let the calling process call 'detach'
beforehand if it needs it.
This commit checks for the currently attached UBI partition, and skips
reattaching if not needed, showing an information.

virtio_init() enumerates all the peripherals that are to be materialised
with udevices(UCLASS_VIRIO) and creates particular device instances
(UCLASS_BlK or whatever else) as children.
On the other hand, device_probe() won't be invoked against those resultant
udevices unlike other ordinary device drivers do in the driver model.
This is particularly inconvenient when we want to add "event notification"
callback so that we will be able to automatically create all efi_disk
objects in a later patch.
With this patch applied, "virtio scan" will work in a similar way
to "scsi rescan", "usb start" or others in term of 'probe' semantics.
I didn't add this change to virtio_init() itself because this function
may be called in board_init_r() (indirectly in board_late_init())
before UEFI subsustem is initialized.

UEFI specification requires that 5 minutes watchdog timer is
armed before the firmware's boot manager invokes an EFI boot option.
This watchdog timer is updated as follows, according to the
UEFI specification.
1) The EFI Image may reset or disable the watchdog timer as needed.
2) If control is returned to the firmware's boot manager,
the watchdog timer must be disabled.
3) On successful completion of EFI_BOOT_SERVICES.ExitBootServices()
the watchdog timer is disabled.
1) is up to the EFI image, and 3) is already implemented in U-Boot.
This patch implements 2), the watchdog is disabled when control is
returned to U-Boot.
In addition, current implementation arms the EFI watchdog at only
the first "bootefi" invocation. The EFI watchdog must be armed
in every EFI boot option invocation.

'pci regions' currently prints only region information from bus 0 which
belongs to controller 0. Parser for 'pci regions' cmdline currently ignores
any additional arguments and so U-Boot always uses bus 0.
Regions are stored in controller (not on the bus) and therefore to retrieve
controller from the bus, it is needed to call pci_get_controller() which
returns root bus. Because bus 0 is root bus, current code worked fine for
controller 0.
Extend cmdline parser for 'pci regions' to allows specifying bus number,
