hw/arm/acpi: simplify AML bit and/or statement
The last argument of AML bit and/or statement is the target variable,
so we don't need to use a NULL target and then an additional store
operation; using just aml_and() or aml_or() statement is enough.
Also update tests/data/acpi/virt/DSDT* to pass "make check".
