mmc_extcsd command: rework ...

This patch is a rework of the mmc_extcsd command:

- Always print registers. Previously we never printed registers that
  were already present in an older version of the spec
- Put register names, access type and width into an array indexed by the
  register number
- Print multibyte registers only once with the resulting value, and not
  bytewise.

There's still more to cleanup, like for example we want to write
multibyte registers once with the complete value, not bytewise. Anyway,
this is a start.

mmc: Consistently use EXT_CSD_* names from eMMC 5.1 spec ...

We have kept the EXT_CSD registers which were added in the 5.1 spec
separately for no good reason. Order the EXT_CSD defines by register
number instead. Also we had some duplicates, for these consistently
use the names from the 5.1 spec.

gpiolib: Add code to support "active low" GPIOs ...

So far this particular aspect of various DT-bindings has been handled
on a per-driver basis. With this change, hopefully, we'll have a
single place to handle necessary logic inversions and eventually
would be able to migrate existing users as well as avoiding adding
redundant code to new drivers.

cdev: make file operations const ...

scripts/checkpatch.pl warns that struct file_operations should be const,
but cdev->ops is not const, so without this patch we can choose between
a warning from checkpatch and a warning from the compiler about
discarding the const attribute when assigning the struct file_operations
cdev->ops.

Since there is no reason to modify the contents of cdev->ops after
probing, make it const.

commands: allow <cmd>_aliases[] to be const ...

Commands with aliases define an array of alias strings such as:

  static const char *<cmd>_aliases[] = { "<alias1>", NULL};

Although the elements are of type `const char *`, the elements
themselves are not `const`-qualified.  If the array is declared as:

  static const char * const <cmd>_aliases[] = { "<alias1>", NULL};

then the compiler warns about const qualifiers being discarded.  This is
because the `aliases` member of `struct command` is declared as `const
char *aliases;`.

Change the declaration of the `aliases` member of `struct command` to
`const char * const *aliases;` so that it can point to a `const` array
of `const char *`.  Also change the declaration of the `aliases`
variable in `register_command()` to avoid unnecessary type casts.

fs: Create automount entries for the default mount pathes ...

In barebox the default mount path for a cdev is /mnt/<cdevname>
which can be mounted with "mount <cdevname>" without specifying
a target path explicitly. Simplify this further by creating automount
entries for the default mount pathes which makes a manual mount
completely unnecessary.

libgen: implement posix_basename ...

There are two different versions of basename(): The GNU version and the
POSIX version. The GNU version never modifies its argument and returns
the empty string when path has a trailing slash, and in particular also
when it is "/". The POSIX version modifies its argument and thus works
properly with strings which have a trailing "/".

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.
