[PATCHv2 03/15] clk: ti: add API for creating aliases automatically for simple clock types

This API generates clock aliases automatically for simple clock types
(fixed-clock, fixed-factor-clock), so that we don't need to add the data
for these statically into tables. Shall be called from the SoC specific
clock init.
