mb/siemens/mc_ehl1: Enable pi608gp I2C driver
Add devicetree and Kconfig entries to enable additional configuration
of the Pericom PI7C9X2G608GP PCIe switch on this board variant.
The amplitude is being adjusted to 425 mV and de-emphasis level to
6.0 mV.
BUG=none
TEST=Read out the PCIe config space values of the switch and check if
they match with the ones configured over SMBus.
