The current CI test worked by sheer luck, the g_dev global pointer
in the fwu library was never initialized and the test equally well
failed on sandbox64. Trigger the main loop in sandbox tests too to
initialize that global state, and move the sandbox specific exit
from fwu_boottime_checks after g_dev is initialized.

Code rewrites the last char of size with adding &. It is visible from
dfu_alt_info print before this patch:
Make dfu_alt_info: 'mtd nor0=bank0 raw 2320000 80000;bank1 raw 27a0000
8000&mtd nor0=bank0 raw 23a0000 4000000;bank1 raw 2820000 4000000'
And after it:
Make dfu_alt_info: 'mtd nor0=bank0 raw 2320000 80000;bank1 raw 27a0000
80000&mtd nor0=bank0 raw 23a0000 4000000;bank1 raw 2820000 4000000'
Size for bank0 and bank1 must be the same because it is the same image.

Current code after capsule update (mtd write) is not changing active_index
in mdata to previous_active_index.
On the reboot this is shown but showing message
"Boot idx 1 is not matching active idx 0, changing active_idx"
which is changing active_idx and writing mdata to flash.
But when this message is visible it is not checking which state that images
are. If they have acceptance bit setup to yes everything is fine and valid
images are booted (doesn't mean the latest one).
But if acceptance bit is no and images are in trial state in_trial variable
is never setup. Which means that from new flashed image stable image can be
rewritten because in_trial is not setup properly.

In the FWU Multi Bank Update feature, the information about the
updatable images is stored as part of the metadata, on a separate
region. Add a driver for reading from and writing to the metadata
when the updatable images and the metadata are stored on a raw
MTD region.
The code is divided into core under drivers/fwu-mdata/ and some helper
functions clubbed together under lib/fwu_updates/

Add test cases for accessing the FWU Metadata on the sandbox
platform. The sandbox platform also uses the metadata access driver
for GPT partitioned block devices.
The FWU feature will be tested on the sandbox64 variant with a raw

the FIT capsule test will be run on the sandbox_flattree variant.

The FWU Multi Bank Update feature supports updating firmware images
to one of multiple sets(also called banks) of images. The firmware
images are clubbed together in banks, with the system booting images
from the active bank. Information on the images such as which bank
they belong to is stored as part of the metadata structure, which is
stored on the same storage media as the firmware images on a dedicated
partition.
At the time of update, the metadata is read to identify the bank to
which the images need to be flashed(update bank). On a successful
update, the metadata is modified to set the updated bank as active
bank to subsequently boot from.

The FWU Multi Bank Update specification requires the Update Agent to
carry out certain checks at the time of platform boot. The Update
Agent is the component which is responsible for updating the firmware
components and maintaining and keeping the metadata in sync.
The spec requires that the Update Agent perform the following checks
at the time of boot
* Sanity check of both the metadata copies maintained by the platform.
* Get the boot index passed to U-Boot by the prior stage bootloader
and use this value for metadata bookkeeping.
* Check if the system is booting in Trial State. If the system boots
in the Trial State for more than a specified number of boot counts,
change the Active Bank to be booting the platform from.
Call these checks through the main loop event at the time of platform
boot.

Add weak functions for getting the update index value and dfu
alternate number needed for FWU Multi Bank update
functionality.
The current implementation for getting the update index value is for
platforms with 2 banks. If a platform supports more than 2 banks, it
can implement it's own function. The function to get the dfu alternate
number has been added for platforms with GPT partitioned storage
devices. Platforms with other storage partition scheme need to
implement their own function.
