platforms/firenze: Fix I2C clock source frequency
The I2C master clock source frequency is hardcoded to wrong value.
The correct frequency should be the nest clock frequency divided
by 16 as Ben said.
This fixes I2C master source frequency with the help of additional
properties "nest-frequency" and "bus-frequency" to root and xscom
device node separately.
