Most of this is duplicated in Kconfig help. Add some of that which is not,
and remove the help from the README.

EXAMPLE: If you want all functions except of network
support you can write:
#include "config_cmd_all.h"
#undef CONFIG_CMD_NET
Other Commands:
fdt (flattened device tree) command: CONFIG_OF_LIBFDT
Note: Don't enable the "icache" and "dcache" commands
(configuration option CONFIG_CMD_CACHE) unless you know
what you (and your U-Boot users) are doing. Data
cache cannot be enabled on systems like the
8xx (where accesses to the IMMR region must be
uncached), and it cannot be disabled on all other
systems where we (mis-) use the data cache to hold an
initial stack and some data.
