soc/intel/common/block/lpc: Move southbridge_write_acpi_tables declaration

Move the southbridge_write_acpi_tables declaration from acpi.h to common
lpc_lib.h, as common LPC is always the caller. This removes a duplicate
declaration since all soc/intel devices use common LPC, but not all use
common ACPI. The southbridge_write_acpi_tables function is defined in acpi.c
with the other acpi functions.

Note that this would have the reverse problem if there is ever a non-common
LPC device.
