[PATCH] acpi: Set TPM2 LAML to actual log area size

["Tu Dinh" <ngoc-tu.dinh@xxxxxxxxxx>]

The LAML field should follow the TCG PFP specification:

The TCG ACPI specification uses the field name "Log Area Minimum
Length", but the field value is the actual log area length reserved by
Platform Firmware, not a lower bound.
