[PATCH v7 11/20] tegra: fdt: Add clock bindings for Tegra2 Seaboard

Add the definition of the oscillator clock frequency and the 32KHz clock.
The latter is provided by a PMIC on I2C which we don't actually use at
present, but we expect this definition to be used in the kernel and want
to keep our .dts the same.

Changes in v6:
- Add new patch to bring in clock bindings to seaboard
Changes in v7:
- Add in i2c pmic information and 32KHz clock
