firmware: ti_sci: Add Initialization of dev_info head node

On K3 devices two drivers ti_sci and ti_sci_dm are supporting firmware
functions. At run time one of driver is used.

Driver ti_sci already initializing head for dev_list in its probe
function, but it was missed in ti_sci_dm driver.

So add head list init support for ti_sci_dm driver.
While at this, move init of list before usages in both functions.
