enhance memory mapped devices esil support

[radare]

Everytime the esil.mdev callback is executed we get the address of memory that is accessed and if the operation is READ or WRITE. but mdev need another 3rd parameter that specifies the value that is written in this address (which can be byte, word, dword,...).

otherwise we cant emulate hw devices

Is it still considered as "good first issue"?
Peeking at the code it looks quite a straightforward change, I am just not sure if changing number of arguments for cmd_mdev requires changes outside esil.c.
