lib: Add getopt

Some commands can get very unweildy if they have too many positional
arguments. Adding options makes them easier to read, remember, and
understand.

This implementation of getopt has been taken from barebox, which has had
option support for quite a while. I have made a few modifications to their
version, such as the removal of opterr in favor of a separate getopt_silent
function. In addition, I have moved all global variables into struct
getopt_context.

The getopt from barebox also re-orders the arguments passed to it so that
non-options are placed last. This allows users to specify options anywhere.
For example, `ls -l foo/ -R` would be re-ordered to `ls -l -R foo/` as
getopt parsed the options. However, this feature conflicts with the const
argv in cmd_tbl->cmd. This was originally added in 54841ab50c ("Make sure
that argv[] argument pointers are not modified."). The reason stated in
that commit is that hush requires argv to stay unmodified. Has this
situation changed? Barebox also uses hush, and does not have this problem.
Perhaps we could use their fix?

I have assigned maintenance of getopt to Simon Glass, as it is currently
only used by the log command. I would also be fine maintaining it.

Allowing denial makes it easier to filter certain subsystems. Unlike
allow-ing filters, deny-ing filters are added to the beginning of the
filter list. This should do the Right Thing most of the time, but it's

works correctly.

However, new of-platdata features rely on numbering the devices in a
particular order so that they can be referenced by a single integer. It is
tricky to implement this efficiently when other devices are present in the
build.

To address this, disable use of U_BOOT_DEVICE() when of-platdata is
enabled. This seems acceptable as it is not supposed to be used at all,
except in SPL/TPL, where of-platdata is the recommended approach.

device, and we can use it to obtain the struct udevice pointer itself.

Since we don't know the struct udevice pointer until it is allocated in
memory, we have to fix up the phandle_n_arg.node at runtime. This is
annoying since it requires that SPL's data is writable and adds a small

Now that we can find a driver_info by its index, it is easier to put the
