[PULL 31/34] hw/arm/acpi: simplify AML bit and/or statement

[Peter Maydell <peter.maydell@linaro.org>]

From: Heyi Guo <guoheyi@huawei.com>

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".
