Tu Dinh 242a5f75ee acpi: Set TPM2 LAML to actual log area size 
The LAML field should follow the TCG PC Client Platform Firmware Profile
Specification Version. Version 1.06 Revision 52 says:

'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.'

Remove the now-unused TPM_LOG_AREA_MINIMUM_SIZE.

No functional change.
