lib/spd_bin,soc/intel/common: Move get_spd_smbus()
Only smbuslib.c and spd_bin.c share the same prototypes for SMBUS functions. Therefore, get_spd_smbus() currently only works with soc/intel/.../smbuslib.c and can be implemented there locally. This allows removal of <device/early_smbus.h>.

-/**
- * @file device/early_smbus.h
- *
- * This file defines a common API for accessing the SMBus during early
- * initialization. It defines the prototypes for common SMBus functions. The
- * actual implementations are hardware-dependent.
- *
- * The first parameter of all SMBus functions take a u32 value smbus_dev which
- * represents some information on how to access the device, and is
- * implementation defined. Usually, it just contains the IO base for the smbus.
- * To get this argument @ref smbus_get_device() can be used.
- *
- * The header only defines the prototypes. Several steps are needed to use
- * these:
- *
- * 1. Include this header
- * @code{.c}
- * #include <device/early_smbus.h>
- * @endcode
- *
- * 2. Implement early_smbus.c for the hardware, or find a compatible
- * implementation.
- *
- * 3. Link against the file that implements these functions. In the Makefile.inc
- * of the chipset, add:
- * @code
- * romstage-y += ./path/to/early_smbus.c
- * @endcode
