When creating the RSDT and the XSDT table they contain no entries.
The table size therefore must equal the header size.
Without this change a NULL deference has been observed in
acpi_find_table() when running `ut dm` on sandbox64_defconfig
executed via `sudo ./u-boot -D`.

Update dm_test_acpi_ctx_and_base_tables() in test/dm/acpi.c to expect
sizeof(struct acpi_table_header) for the initial table length (instead
of sizeof(*rsdt) / sizeof(*xsdt)), and to compute the checksum over
header->length bytes rather than the full struct size:
