Move the fixup code where the parser code is already.
Since the code will not only be used for mtd in the future
drivers/of/ is a better place than drivers/mtd/.

The globalvar_add_simple_* functions will fail when a globalvar of
the name already exists. This happened when the globalvar was created
previously because a corresponding nvvar existed. For this reason we
removed the globalvars that have been previously created by nvvar
creation (we called these unqualified globalvars). Since we no longer
create the corresponding globalvars on nvvar creation this code is
no longer needed. Remove it.

Some boards that boot directly from C code do already know that
they want to boot from bootchooser and nothing else. For these
it's easiest to call bootchooser_boot directly, so export this
function.

bootentry_create_from_name() takes a name and creates bootentries
for it. It tries different providers that interpret the name:
blspec, bootchooser or script pathes. Instead of hardcoding the
different providers in the function, allow the providers to register
themselves.

We used to have a static array of trigger types which, allows only one led
per trigger. While this is enough for panic and heartbeat, it falls short when
multiple leds are associated to the default-on trigger. The default-on trigger
is used to turn on a led statically from devicetree and may be used multiple
times.
This patch reworks the led triggers so that a trigger struct is allocated
dynamically when needed and put onto a list.

So far blinking/flashing LEDs is only supported on led-trigger level.
Even without triggers it useful to be able to blink/flash LEDs, so
add this functionality to the LED core.
A led_blink_pattern consists of a number of on and off-periods which
are described in an array. Using such an array you can encode nearly
every blink pattern you need.

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.

Convert mci_of_parse into mci_of_parse_node, a function that takes
explicit deivce tree node pointer to be used for SD/MMC related
properties extraction. Implement original mci_of_parse as a wrapper
around the call to new function.
This is useful for controllers who specify parameter like bus witdth and
GPIOs as a part of main controller's child nodes (e.g. AT91 SoCs).

The usbgadget commands uses statically allocated f_multi_opts and passes
this to usb_multi_register(). These f_multi_opts are of course no
longer valid when we leave the usbgadget command. Luckily we do not use
the data after we left the usbgadget command, so this never has been a
problem. However, f_multi_opts has some allocated members which we can
not free anymore on gadget unregistration because we no longer have the
pointer to them.
Fix this by adding a release function to struct f_multi_opts. This way
we can allocate all memory dynamically and properly free it when not
used anymore.
