ir: add toshiba protocol support [1/1]

Browse Source 
PD#SWPL-3543

Problem:
current driver does not support toshiba ir remote control protocol

Solution:
add register setting and decode code for toshiba protocol
use REMOTE_TYPE_TOSHIBA/REMOTE_TYPE_NEC_TOSHIBA to configure toshiba
only/toshiba and nec.

Verify:
