clk: st: Remove impossible check for of_clk_get_parent_count() < 0
The checks for < 0 are impossible now that of_clk_get_parent_count() returns an unsigned int. Simplify the code and update the types. Cc: Gabriel Fernandez <gabriel.fernandez@st.com> Signed-off-by: Stephen Boyd <sboyd@codeaurora.org>
