common/block/imc: Add Integrated Memory Controller (IMC) driver
IMC is found on certain Xeon processors. On such platforms SPDs are not
connected to SMBus on PCH but to dedicated IMC-owned pins. The purpose
of this driver is to expose access to the i2c/smbus controller associated
with IMC.
Datasheet used: Intel Xeon Processor D-1500 Product Family, Volume 2,
reference 332051-001
This driver is largely based on i2c-imc.c Linux driver.

TEST=single/double reads and single writes on Xeon-D1500.
Hardware: Open Compute Project Monolake platform.
