This adds a convenience function to register a MAC address device
parameter. The only current user is converted to use it.

We recently gained helper functions for different types of
device parameters. One thing missing was a helper for an
enum type parameter. This patch adds this.

Some parameters may wish to provide some information about their
meaning or possible values. Provide an info callback for parameters.

This adds convenience functions for directly registering integers
and bools as device parameter. This way driver no longer have to
fiddle with string handling. The format used to print the parameter
is passed to the functions to be able to print parameters in a
flexible way.

Commit 51f2ded17c ("param: make return
value of param getter function const") made the parameter getter const,
but neglected to change the dev_add_param() function prototype in the
!CONFIG_PARAMETER case.
Fixes the following warning with CONFIG_NAND and !CONFIG_PARAMETER:
drivers/mtd/nand/nand_base.c: In function 'add_mtd_nand_device':
drivers/mtd/nand/nand_base.c:1720:2: warning: passing argument 4 of 'dev_add_param' from incompatible pointer type [enabled by default]
include/param.h:59:19: note: expected 'char * (*)(struct device_d *, struct param_d *)' but argument is of type 'const char * (*)(struct device_d *, struct param_d *)'

Change device parameters so that the memory management is in generic
code. This also removes the need of storing statically initialized
parameters as they are stored in a struct list_head for each device.
