MA-20017 Disable clocks only when CONFIG is enabled

In the following patch, we only open the clks that LPA can use
after enabling the M core:

MA-18346-25 0nly for M7 LPA required CCM slice, skip controlled by A53

Because we only achieved LPA on 8mm and 8mp. Therefore, it will cause
problems when M core is enabled on 8mq and 8mn. So I add a CONFIG to
distinguish.

At the same time, if the M core of the 8m* board wants to achieve not
only the function of LPA, but also the clk used to be added to
static char *m4_lpa_required_ccm_slices[ ].
