The Flexcom IP is part of the sama5d2 SoC. Move the flx0 node together
with its function definitions in sama5d2.dtsi. Boards will just fill
the pins and enable the desired functions.

There is an EEPROM on at91-sama5d27_som1 connected to i2c0. i2c0 node
has to be moved from at91-sama5d27_som1_ek to at91-sama5d27_som1.
Enable the i2c EEPROM found on at91-sama5d27_som1. Add an alias for the
