clk: mb86s7x: Drop non-building driver

It fails to build once we introduce the ARCH_MB86S7X Kconfig symbol:

  drivers/clk/clk-mb86s7x.c:27:10: fatal error: soc/mb86s7x/scb_mhu.h: No such file or directory
   #include <soc/mb86s7x/scb_mhu.h>
            ^~~~~~~~~~~~~~~~~~~~~~~
  compilation terminated.

And when commenting out that line, we get:

Remove the driver for now.
