msm: camera: utils: Add option to not set src clk rate

Clients like cpas scale some clocks like slow_ahb, fast_ahb
through vote level based on other hw's src clk freq while
the actual src clock (camnoc) is calculated and set directly
through set_src_clk API. This will overwrite freq of camnoc_axi
with the same level as AHB when ahb clocks are set. Do not
set src clk rate while setting rate for other clocks using level.
