mediatek: mt7623: backport musb, improve HDMI console

Backport support for dual-role USB 2.0 as that's what is actually
built-into MT7623.
Improve HDMI console by enabling VT and setting up tty1..tty6.
Re-add accidentally removed CONFIG_ARM_ARCH_TIMER.

+-MediaTek musb DRD/OTG controller
+--------------------------------------------
+-
+-Required properties:
+- - compatible      : should be one of:
+-                     "mediatek,mt2701-musb"
+-                     ...
+-                     followed by "mediatek,mtk-musb"
+- - reg             : specifies physical base address and size of
+-                     the registers
+- - interrupts      : interrupt used by musb controller
+- - interrupt-names : must be "mc"
+- - phys            : PHY specifier for the OTG phy
+- - dr_mode         : should be one of "host", "peripheral" or "otg",
+-                     refer to usb/generic.txt
+- - clocks          : a list of phandle + clock-specifier pairs, one for
+-                     each entry in clock-names
+- - clock-names     : must contain "main", "mcu", "univpll"
+-                     for clocks of controller
+-
+-Optional properties:
+- - power-domains   : a phandle to USB power domain node to control USB's
+-                     MTCMOS
+-
+-Required child nodes:
+- usb connector node as defined in bindings/connector/usb-connector.yaml
+-Optional properties:
+- - id-gpios        : input GPIO for USB ID pin.
+- - vbus-gpios      : input GPIO for USB VBUS pin.
+- - vbus-supply     : reference to the VBUS regulator, needed when supports
+-                     dual-role mode
+- - usb-role-switch : use USB Role Switch to support dual-role switch, see
+-                     usb/generic.txt.
+-
+-Example:
+-
+-usb2: usb@11200000 {
