platform/x86/amd/pmf: Switch to platform_get_resource() and devm_ioremap_resource()
Use platform_get_resource() to fetch the memory resource instead of
acpi_walk_resources() and devm_ioremap_resource() for mapping the
resources.
PS: We cannot use resource_size() here because it adds an extra byte to
round off the size. In the case of PMF ResourceTemplate(), this rounding
is already handled within the _CRS. Using resource_size() would increase
the resource size by 1, causing a mismatch with the length field and
leading to issues. Therefore, simply use end-start of the ACPI resource to
obtain the actual length.
