platform/x86/amd/hsmp: Validate _DSD mailbox sub-package element count
hsmp_read_acpi_dsd() dereferenced elements[0] and elements[1] of each
mailbox sub-package before confirming the package actually held two
elements, allowing an out-of-bounds read on a malformed _DSD.
Verify package.count >= 2 first, then fetch the string and integer
objects.
