Subject: [PATCH] acpi: Replace struct acpi_table_slit 1-element array with flex-array

struct acpi_table_slit is used for copying System Locality Information
Table data from ACPI tables. Here `entry` is a flex array but it was
using ancient 1-element fake flexible array, which has been deprecated.
Replace it with a C99 flexible array.
