drivers: i2s: Add support for nRF I2S peripherals Add a shim that allows using the nrfx I2S driver via the Zephyr API. Add also missing devicetree nodes representing the I2S peripherals in the nRF52 Series SoCs. Extend the "nordic,nrf-i2s" binding with a new property that allows specifying the clock source to be used by the I2S peripheral (so that it is possible to use HFXO for better accurracy of the peripheral clock or, in the nRF53 Series SoCs, to use the dedicated audio oscillator).

soc: nrf: Use data from DTS to populate HAS_HW_NRF_* Kconfig options Instead of selecting appropriate HAS_HW_NRF_* options for particular nRF SoCs (and simulated nRF52 target), set their values basing on information from devicetree. Correct also semantics of those options so that they are set only when a corresponding DT node is enabled. This allows using them directly in Kconfig dependencies of Zephyr drivers for nRF peripherals. Update appropriately these dependencies. Signed-off-by: Andrzej Głąbek <andrzej.glabek@nordicsemi.no>
