clk-bpmp: Use conftest to determine clk_hw_determine_rate_no_reparent()

Browse Source 
The clock ops needs the determine_rate() callback in clock ops if
set_parent() is needed by commit 33b70fbc4f815f("clk: Introduce
clk_hw_determine_rate_no_reparent()") and commit 326cc42f9fdc3
("clk: Forbid to register a mux without determine_rate")
from Linux 6.4.

Add conftest method to determine if clk_hw_determine_rate_no_reparent()
present.
