df3dc20952 x86: Drop unnecessary mp_init logic
Now that sequence numbers are set up when devices are bound, this code is
not needed. Also, we should use dev_seq() instead of req_seq. Update the
whole file accordingly.

Also fix up APL cpu while we are here.

6571d87315 x86: apl: Add core init for the SoC
Set up MSRs required for Apollo Lake. This enables Linux to use the
timers correctly. Also write the fixed MSRs for this platform.

9d20db0483 x86: Fix up driver names to avoid dtoc warnings
At present there are a lot of dtoc warnings reported when building
chromebook_coral, of the form:

   WARNING: the driver intel_apl_lpc was not found in the driver list

Correct these by using driver names that matches their compatible string.

961420fa5f cpu: Convert the methods to use a const udevice *
These functions should not modify the device. Convert them to const so
that callers don't need to cast if they have a const udevice *.

2c64d11e32 x86: apl: Use cpu_x86_get_count() for cpu_ops.get_count
Use cpu_x86_get_count() to read the number of cores.

cpu_x86_get_count() reads the number of CPUs from the device tree.
Using this function we can support multiple Apollo Lake
variants, e.g.: E3940 (4 cores) and E3930 (2 cores).

This was tested on the E3940 and E3930 Apollo Lake variants.
