libstb: import stb_init() breaking it into multiple files

This imports stb_init() from stb.c, but breaking it into multiple files
in order to make the code easier to read and to maintain. New files
created: secureboot.c, trustedboot.c and cvc.c.

The secureboot_init() in secureboot.c also initializes the hardware key
hash and the hardware key hash size, which are used to call the CVC
verify wrapper. These variables were initialized in the romcode_probe()
function, libstb/drivers/romcode.c.

The cvc_init() in cvc.c is slightly modified from what exists in
stb_init(). Now it calls cvc_register() and cvc_service_register().
