clk: qcom: use different Kconfig prompts for APSS IPQ5424/6018 drivers

Both the IPQ_APSS_5424 and IPQ_APSS_6018 symbols are using the same
prompt which complicates to see that which option corresponds to which
driver.

Add a prefix to both prompts to make it easier to differentiate the
two options.

While at it, also fix a typo in the help text of the IPQ_APSS_5424
symbol.
