doc: usb: remove obsolete MediaTek MTU3 bindings

The MediaTek MTU3 and xHCI text bindings describe legacy U-Boot layouts
which have been superseded by the canonical Linux schemas. Those schemas
are already synchronized into `dts/upstream/Bindings/usb`.

Remove the duplicate text bindings so new devicetrees and driver changes
use the maintained YAML definitions.

-The device node for Mediatek USB3 DRD controller
-
-Required properties:
- - compatible : should be "mediatek,<soc-model>-mtu3", "mediatek,mtu3",
-	soc-model is the name of SoC, such as mt8512 etc,
-	when using "mediatek,mtu3" compatible string, you need SoC specific
-	ones in addition, one of:
-	- "mediatek,mt8512-mtu3"
- - reg : specifies physical base address and size of the registers
- - reg-names: should be
-	- "ippc" : IP Port Control
- - power-domains : a phandle to USB power domain node to control USB's MTCMOS
- - clocks : a list of phandle + clock-specifier pairs, one for each
-	entry in clock-names
- - clock-names : must contain "sys_ck" for clock of controller,
-	the following clocks are optional:
-	"ref_ck", "mcu_ck", "dma_ck" and "xhci_ck";
- - phys : list of all the USB PHYs on this HCD
- - #address-cells, #size-cells : used for sub-nodes with 'reg' property
- - ranges : allows valid 1:1 translation between child's address space and
-	parent's address space
-
-Optional properties:
- - vusb33-supply : regulator of USB AVDD3.3v
- - vbus-supply : regulator of VBUS 5v, needed when supports host mode.
-
-Sub-nodes:
-Required properties:
- - compatible : should be "mediatek,ssusb"
- - reg : specifies physical base address and size of the registers
- - reg-names: should be
-	- "mac" : SSUSB MAC, include xHCI and device
- - interrupts : interrupt used by xHCI or device
- - dr_mode : should be one of "host" or "peripheral",
-	see : usb/generic.txt
-
-Optional properties:
- - pinctrl-names : a pinctrl state named "default" is optional
- - pinctrl-0 : pin control group
-	See: pinctrl/pinctrl-bindings.txt
-
- - device mode:
-   - maximum-speed : valid arguments are "full-speed", "high-speed",
-	"super-speed" and "super-speed-plus",
-	see: usb/generic.txt
-   - mediatek,force-vbus : force vbus as valid by SW
