Merge branch 'lpc32xx/dt' of https://github.com/vzapolskiy/linux into next/dt

Merge DT changes for lpc32xx from Vladimir Zapolskiy:

"The changes add description of clock providers and clock consumers,
define default irq types of SoC controllers and add PHY3250 board
regulators.

I'm adding an official LPC32xx maintainer Roland to Cc, however he seems
to be unresponsive for a quite long time (since 2014)."
