x86: Add a clock driver for Intel devices
So far we have avoided adding a clock driver for Intel devices. But the
Designware I2C driver needs a different clock (133MHz) on Intel devices
than on others (166MHz). Add a simple driver that provides this
information.
This driver can be expanded later as needed.
