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.
