platform/x86/amd/hsmp: Make amd_hsmp and hsmp_acpi as mutually exclusive drivers
amd_hsmp and hsmp_acpi are intended to be mutually exclusive drivers and
amd_hsmp is for legacy platforms. To achieve this, it is essential to
check for the presence of the ACPI device in plat.c. If the hsmp ACPI
device entry is found, allow the hsmp_acpi driver to manage the hsmp
and return an error from plat.c.

Additionally, rename the driver from amd_hsmp to hsmp_acpi to prevent
"Driver 'amd_hsmp' is already registered, aborting..." error in case
both drivers are loaded simultaneously.

Also, support both platform device based and ACPI based probing for
family 0x1A models 0x00 to 0x0F, implement only ACPI based probing
for family 0x1A, models 0x10 to 0x1F. Return false from
legacy_hsmp_support() for this platform.
This aligns with the condition check in is_f1a_m0h().

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
