The Raspberry Pi Panel V2 regulator driver may rely on an external power rail being provided through the device tree. Add support for an optional "vcc" regulator and enable it during probe before accessing the panel controller. This ensures the panel controller is powered before I2C communication is attempted while maintaining backward compatibility with existing platforms.

Add a DT overlay to switch Talos Lyra EVK display output from the LT9611 HDMI bridge to the DLC0697 MIPI-DSI panel connected through the B2B DSI interface. The overlay: - Disables the LT9611 HDMI bridge and HDMI connecto - Adds the DLC0697 panel node on mdss_dsi0 - Configures a 4-lane DSI connection - Sets up panel reset (GPIO118) and backlight enable (GPIO2) - Enables panel TE on GPIO98 (mdp_vsync) - Connects panel power supplies: - vreg_s4a (1.8V VDDIO) - vreg_disp_3p3 (LCD bias) This allows the DLC0697 panel to be used in place of the default HDMI display path on Talos Lyra EVK.

Add a device tree overlay to support the Raspberry Pi 7-inch DSI display on Talos Lyra EVK through the B2B DSI connector. The overlay: - Disables the LT9611 HDMI bridge and HDMI connector - Adds Raspberry Pi DSI 7-inch panel support on mdss_dsi0 - Configures the panel regulator/backlight controller at I2C address 0x45 - Adds pwm-backlight support using the Raspberry Pi touchscreen regulator device - Reconfigures vreg_disp_3p3 to use expander0 GPIO1 for panel power - Connects panel supplies, reset GPIO, and backlight controls - Configures a 2-lane DSI interface - Adds DTB build target for the Raspberry Pi DSI display variant This enables use of the Raspberry Pi 7-inch display instead of the default HDMI display path on Talos Lyra EVK.
