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.

pinctrl: Remove DM_FLAG_PRE_RELOC flag in various drivers

When a driver declares DM_FLAG_PRE_RELOC flag, it wishes to be
bound before relocation. However due to a bug in the DM core,
the flag only takes effect when devices are statically declared
via U_BOOT_DEVICE(). This bug has been fixed recently by commit
"dm: core: Respect drivers with the DM_FLAG_PRE_RELOC flag in
lists_bind_fdt()", but with the fix, it has a side effect that
all existing drivers that declared DM_FLAG_PRE_RELOC flag will
be bound before relocation now. This may expose potential boot
failure on some boards due to insufficient memory during the
pre-relocation stage.

To mitigate this potential impact, the following changes are
implemented:

- Remove DM_FLAG_PRE_RELOC flag in the driver, if the driver
  only supports configuration from device tree (OF_CONTROL)
- Keep DM_FLAG_PRE_RELOC flag in the driver only if the device

- Surround DM_FLAG_PRE_RELOC flag with OF_CONTROL check, for

Currently the sandbox block driver uses priv_auto_alloc_size for
the driver data, however that's only available after the device
probe phase. In order to make it accessible in an earlier phase,
switch to use platdata_auto_alloc_size instead.

This patch is the prerequisite for the follow up patch of DM BLK
driver changes to work with Sandbox.

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.
