[PATCH v2] cmd: pxe_utils: sysboot: replace cls command by video_clear in PXE parser

Since the commit bfaa51dd4adf ("cmd: add serial console support for the cls command") the cls command is not enough to clear the video display when ANSI console is activated.
This patch clears the video device with the video_clear() API before to display the bitmap used for the PXE background.
This patch avoids to display the LOGO, activated by default with commit 7a8555d87136 ("video: Show the U-Boot logo by default").

To avoid parameter issue for video_clear(dev) function: no parameter dev when CONFIG_DM_VIDEO is deactivated.
Changes in v2: - move #include <dm.h> to avoid compilation issue when CONFIG_DM_RNG is not activated for uclass_first_device_err - Avoid error too many arguments to function 'video_clear' when CONFIG_DM_VIDEO is not activated, use: #if defined(CONFIG_DM_VIDEO)
