dt-bindings: Remove PicoXcell bindings

PicoXcell has had nothing but treewide cleanups for at least the last 8
years and no signs of activity. The most recent activity is a yocto vendor
kernel based on v3.0 in 2015.

-Picochip picoXcell device tree bindings.
-========================================
-
-Required root node properties:
-    - compatible:
-       - "picochip,pc7302-pc3x3" : PC7302 development board with PC3X3 device.
-       - "picochip,pc7302-pc3x2" : PC7302 development board with PC3X2 device.
-       - "picochip,pc3x3" : picoXcell PC3X3 device based board.
-       - "picochip,pc3x2" : picoXcell PC3X2 device based board.
-
-Timers required properties:
-    - compatible = "picochip,pc3x2-timer"
-    - interrupts : The single IRQ line for the timer.
-    - clock-freq : The frequency in HZ of the timer.
-    - reg : The register bank for the timer.
-
-Note: two timers are required - one for the scheduler clock and one for the
-event tick/NOHZ.
-
-VIC required properties:
-    - compatible = "arm,pl192-vic".
-    - interrupt-controller.
-    - reg : The register bank for the device.
-    - #interrupt-cells : Must be 1.

-Picochip picoXcell SPAcc (Security Protocol Accelerator) bindings
-
-Picochip picoXcell devices contain crypto offload engines that may be used for
-IPSEC and femtocell layer 2 ciphering.
-
-Required properties:
-  - compatible : "picochip,spacc-ipsec" for the IPSEC offload engine
-    "picochip,spacc-l2" for the femtocell layer 2 ciphering engine.
-  - reg : Offset and length of the register set for this device
-  - interrupts : The interrupt line from the SPAcc.
-  - ref-clock : The input clock that drives the SPAcc.
-
-Example SPAcc node:
-
-spacc@10000 {
-       compatible = "picochip,spacc-ipsec";
-       reg = <0x100000 0x10000>;
-       interrupt-parent = <&vic0>;
-       interrupts = <24>;
-       ref-clock = <&ipsec_clk>, "ref";
