soc/intel/pantherlake: Comply with the no typedef coding style rule

As https://doc.coreboot.org/contributing/coding_style.html#typedefs
states: "In general, a pointer, or a struct that has elements that can
reasonably be directly accessed should never be a typedef". This
commit makes the Intel Panther Lake SoC code comply with this by using
explicitly `struct soc_intel_pantherlake_config' in the
soc/intel/pantherlake code as I have been suggested to for the
`fsp_params.c' files. The rule being the rule and consistency across
a project matters more than personal preferences.

The documentation lists five exceptions and none on them cover the use
of `config_t' instead `struct soc_intel_pantherlake' but I believe it
does not make the code better for the following three reasons:

1. It is repetitive, make the line longer and the code is in
   soc/intel/pantherlake so obviously the config_t data structure is
   the pantherlake soc configuration.

2. It makes re-usability from one generation to another unnecessarily
   harder.

3. This config_t abstraction is required for and used by some common
   block code anyway. Hence, we end-up with some code using `config_t'
   and other using the final structure which break the consistency of
   the code when the project in looked as a whole.
