globalvar: make globalvar functions more consistent ...

Similar to the device parameter functions also make the globalvar
functions more consistent. This also adds support for readonly
globalvars and changes several existing globalvars which should
really be readonly to readonly.

param: make parameter functions more consistent ...

This patch creates a consitent set of device parameter functions.

With this we have: dev_add_param_<type><access>

"type" is one of: int32, uint32, int64, uint64, string, mac, ipv4, enum, bitmask
The improvement here is that we now can exactly specify the width of the
int type parameters and also correctly distinguish between signed and
unsigned variables which means that a variable no longer ends up with
INT_MAX when it's assigned -1.

"access" can be empty for regular read/write parameter, "_ro" for readonly
parameters which get their value from a variable pointer in the
background or "_fixed" for parameters which are set to a fixed value
(without a pointer in the background).

Some more exotic types are not (yet) implemented, like
dev_add_param_ip_ro.

i.MX: hab: Add HAB fusebox related convenience functions / command ...

Secure boot with HAB requires handling of the super root key hash
and actually locking down the device. The related information is
stored in the i.MX fusebox device (IIM on older SoCs, OCOTP on newer
SoCs). This patch adds several convenience functions to store and
read the super root key hash and to lock down a SoC. Also we add
a command to do this from the command line.

When no monitor is connected it might be normal that no modes are found.
Do not bail out with an error in this case, which gives an ugly error

user a chance to examine it and see that the framebuffer has no modes.

of: of_path: add of_find_node_by_devpath() ...

We already have of_find_path_by_node() which finds a device path
for a given device node. This is used by the state framework to
find its backend path. This path has to be translated back to
a device node when Linux is started. The current approach turned
out to be too simple: We assumed that the node path is the same
in the tree Linux is started with. This is not true in several
cases:
- partition nodes should have the name "partition@<offset>", but
  in several trees they have "partition@<num>"
- There are two different partition bindings: The legacy binding
  and the new one with an additional partitions subnode which has
  a compatible = "fixed-partitions" property.
The node path only stays the same when the internal tree uses the
same bindings and node names as the tree Linux is started with.

To overcome this limitation we create of_find_node_by_devpath()
which converts the device path back to a device node. It does
so by finding the device node of the hardware device rather than
the partition node. It then parses over the partitions in this
device node with the known bindings looking for a partition which
matches in offset and size to the barebox partition.

of: partition: only create partition node when partitions exist ...

With the legacy partition binding we did not modify the device
node when no partition exist, but with the new binding we would
create the "partitions" node with compatible = "fixed-partitions".
Prevent that by catching the absence of partitions early.
