    ACPICA: Add AML_NO_OPERAND_RESOLVE flag to Timer
    
    [ Upstream commit 3a21ffdbc825e0919db9da0e27ee5ff2cc8a863e ]
    
    ACPICA commit 90310989a0790032f5a0140741ff09b545af4bc5
    
    According to the ACPI specification 19.6.134, no argument is required to be passed for ASL Timer instruction. For taking care of no argument, AML_NO_OPERAND_RESOLVE flag is added to ASL Timer instruction opcode.
    
    When ASL timer instruction interpreted by ACPI interpreter, getting error. After adding AML_NO_OPERAND_RESOLVE flag to ASL Timer instruction opcode, issue is not observed.
