Add specific dais name when components are registered. Component and dai name will follow their parent dev name, if the name isn't described. In case of this driver, each dais will have same name like '11440000.i2s0' by fmt_single_name function.
The problem having same name is that TM2 machine driver can't detect capture devices correctly. Machine driver doesn't know which one is proper to use for cpu dai. The driver just selects to use 'samsung-i2c-sec' that doesn't have capture functionality because the component of samsung-i2s-sec is located in the first of the component_list.
I add dai name like 'samsung-i2s', 'samsung-i2s-sec' for each dais. The reason why adding dai id to 1 is that it doesn't allow to use particular dai name in case of when I use 0 for dai id.
