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.

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).
