clk: Fix invalid execution of clk_set_rate

Some clocks have rates that can be changed elsewhere, so add a flag
CLK_GET_RATE_NOCACHE(such as scmi_clk) to these clocks to ensure that
the real-time rate is obtained.

When clk_set_rate is called, it is returned if the request to set rate
is consistent with the current rate. Getting the current rate in
clk_set_rate returns the rate stored in clk_core. CLK_GET_RATE_NOCACHE
does not take effect here.
