In a number of cases we have C files which rely on a chain of indirect
include paths to get <linux/string.h> to be included via <command.h>. To
facilitate cleaning up <command.h> make this code directly include
<linux/string.h>.

When the `optee hello' subcommand is called, the do_optee_hello_world_ta()
function passes a NULL pointer to the strcmp() function while verifying its
input argument, which results in the following crash:
=> optee hello
"Synchronous Abort" handler, esr 0x96000010, far 0x0
Fix this by verifying the number of input arguments instead.
Fixes: e3cf80fbe02d ("cmd: Add support for optee commands")

Add the basic 'hello world ta' command which increment
of the value passed. This provides easy test for
establishing a session with OP-TEE TA and verify.
It includes following "hello world ta" subcommands:
optee hello; default value '0' is passed and gets incremented.
optee hello <value>; value to increment via OP-TEE HELLO
WORLD TA.
To enable the OP-TEE side HELLO WORLD example please refer
