dt-bindings: Remove Netlogic bindings

Support for Netlogic was removed in commit 95b8a5e0111a ("MIPS: Remove
NETLOGIC support"). Remove the now unused bindings.

The GPIO binding also includes "brcm,vulcan-gpio", but it appears to be
unused as well as Broadcom Vulkan became Cavium ThunderX2 which is ACPI
based.

-Netlogic XLP Family GPIO
-========================
-
-This GPIO driver is used for following Netlogic XLP SoCs:
-       XLP832, XLP316, XLP208, XLP980, XLP532
-This GPIO driver is also compatible with GPIO controller found on
-Broadcom Vulcan ARM64.
-
-Required properties:
--------------------
-
-- compatible: Should be one of the following:
-  - "netlogic,xlp832-gpio": For Netlogic XLP832
-  - "netlogic,xlp316-gpio": For Netlogic XLP316
-  - "netlogic,xlp208-gpio": For Netlogic XLP208
-  - "netlogic,xlp980-gpio": For Netlogic XLP980
-  - "netlogic,xlp532-gpio": For Netlogic XLP532
-  - "brcm,vulcan-gpio": For Broadcom Vulcan ARM64
-- reg: Physical base address and length of the controller's registers.
-- #gpio-cells: Should be two. The first cell is the pin number and the second
-  cell is used to specify optional parameters (currently unused).
-- gpio-controller: Marks the device node as a GPIO controller.
-- nr-gpios: Number of GPIO pins supported by the controller.
-- interrupt-cells: Should be two. The first cell is the GPIO Number. The
-  second cell is used to specify flags. The following subset of flags is
-  supported:
-  - trigger type:
-       1 = low to high edge triggered.
-       2 = high to low edge triggered.
-       4 = active high level-sensitive.
-       8 = active low level-sensitive.
-- interrupts: Interrupt number for this device.
-- interrupt-controller: Identifies the node as an interrupt controller.
-
-Example:
-
-       gpio: xlp_gpio@34000 {
-               compatible = "netlogic,xlp316-gpio";
-               reg = <0 0x34100 0x1000
-                      0 0x35100 0x1000>;
-               #gpio-cells = <2>;
-               gpio-controller;
-               nr-gpios = <57>;

-               #interrupt-cells = <2>;
-               interrupt-parent = <&pic>;
-               interrupts = <39>;
-               interrupt-controller;

-SPI Master controller for Netlogic XLP MIPS64 SOCs
-==================================================
-
-Currently this SPI controller driver is supported for the following
-Netlogic XLP SoCs:
-       XLP832, XLP316, XLP208, XLP980, XLP532
-
-Required properties:
-- compatible           : Should be "netlogic,xlp832-spi".
-- #address-cells       : Number of cells required to define a chip select address
-                         on the SPI bus.
-- #size-cells          : Should be zero.
-- reg                  : Should contain register location and length.
-- clocks               : Phandle of the spi clock
-- interrupts           : Interrupt number used by this controller.

-SPI slave nodes must be children of the SPI master node and can contain
-properties described in Documentation/devicetree/bindings/spi/spi-bus.txt.
