fdt_region: Ensure that depth never goes below -1
A specially crafted FIT image makes it possible to overflow the stack
with controlled values when using the verified boot feature. Depending
on the memory layout, this could be used to overwrite configuration
variables on the heap and setting them to 0, e.g. disable signature
verification, thus bypassing it.
This change fixes a bug in fdt_find_regions where the fdt structure is
parsed. A lower value than -1 of depth can lead to a buffer underflow
write on the stack.

Ability to modify distro boot filename
Add in the ability to modify the distro boot filename. Whilst not
immediately useful in normal usage, it allows an alternative
configuration to be provided when other u-boot functionality is used, such
as bootcount limit, to fallback to an alternative boot configuration. In
this case we can follow the same boot path as for normal boot, just
using an alternatively named configuration file.
For example, by providing the following `altbootcmd` when bootcount is in
use:
altbootcmd=setenv boot_extlinx_conf extlinux-rollback.conf; \

riscv: qemu: Enumerate virtio bus during early boot
Currently devices on the virtio bus is not automatically enumerated,
which means peripherals on the virtio bus are not discovered by their
drivers. This uses board_init() to do the virtio enumeration.

blk: Call part_init() in the post_probe() method
part_init() is currently called in every DM BLK driver, either
in its bind() or probe() method. However we can use the BLK
uclass driver's post_probe() method to do it automatically.
Update all DM BLK drivers to adopt this change.

efi_driver: blk: Switch to use platdata_auto_alloc_size for the driver data
Currently the efi block driver uses priv_auto_alloc_size for the

to use platdata_auto_alloc_size instead.
This patch is the prerequisite for the follow up patch of DM BLK

test: dm: blk: Correct blk_base test case
The blk_base test case creates a USB mass storage block device with
the Sandbox host block device as its parent. This does not make any
sense and causes potential issue, for example if the test case tries
to read/write anything on the USB mass storage block device it will
definitely fail as its parent is not on USB bus at all.
Correct the test case by creating another Sandbox host block device
instead of the USB mass storage one and adjust the case accordingly.
