lynxpoint: fix mem corruption during ssdt2 gen
The ssdt2 generation code was calling acpigen_patch_len().
However, none of the entries had AML object lengths that
needed patching. That resulted in the following message:
ASSERTION FAILED: file 'src/arch/x86/boot/acpigen.c', line 52
Additionally, this caused an errant write to a memory address
whose value was in the variable ltop. This was the 0 address.
