src: Remove blank acpi_tables source files

Due to build rules, dummy acpi_tables source files were added in many
mainboards. With commit 1e83e5c61a3aa98f58f7d8cbf8d1eb9532896cc3
("src/arch/x86: Build mainboard acpi_tables source if present"),
the build system will build mainboard acpi_tables only if present. Remove
the dummy/empty/blank acpi_tables source files.

BUG=None
TEST=Build test with some google mainboards.
