clk: qcom: clk-cpu-osm: Use CLK_GET_RATE_NOCACHE

After a CPU comes online, clk_set_rate silently refuses to change said CPU's
frequency to the frequency it was running at before going offline (since it
thinks that we are setting the same frequency redundantly). By default, each CPU
runs at its minimum frequency when coming online, so if the governor decides to
keep a CPU running at the frequency it used before going offline, then
clk_set_rate will ignore the frequency change request and the CPU will stay
stuck running at its minimum frequency for a potentially long period of time
(i.e., until the governor decides to change the frequency to something
different). This can cause severe lag when a device is woken up from deep sleep.

In order to prevent a CPU from being stuck at its default frequency for a
potentially long period of time, set the CLK_GET_RATE_NOCACHE flag so that the
governor's frequency change requests will always be honored. Do this for the L3
clock as well.
