Subject: [PATCH v3 1/4] arm: dts: nxp: lpc: lpc32xx: drop 'clocks' form rtc

The RTC does not provide a controllable clock signal (it uses a fixed
32768 Hz crystal, the input clock of the SoC). Remove the 'clocks'
property to better describe the device and avoid errors when checking
the dts against the nxp,lpc3220-rtc binding.
