[PATCH V7 01/14] drivers: video: Kconfig: Add configs for enabling video at SPL

[Nikhil M Jain <n-jain1@ti.com>]

Add Kconfigs which enable the video driver and splash screen at SPL
stage only and not at u-boot proper. The existing Kconfigs from u-boot
proper were not used to make SPL splash screen independent to them.

+	  The video subsystem adds a small amount of overhead to the image.

+	hex "Default framebuffer size to use if no drivers request it at SPL"
+	default 0x1000000 if X86 && PCI
+	default 0 if !(X86 && PCI)
+	help
+	  Generally, video drivers request the amount of memory they need for
+	  the frame buffer when they are bound, by setting the size field in
+	  struct video_uc_plat. That memory is then reserved for use after
+	  relocation. But PCI drivers cannot be bound before relocation unless
+	  they are mentioned in the devicetree.
+
+	  With this value set appropriately, it is possible for PCI video
+	  devices to have a framebuffer allocated by U-Boot.
+
+	  Note: the framebuffer needs to be large enough to store all pixels at
+	  maximum resolution. For example, at 1920 x 1200 with 32 bits per
+	  pixel, 2560 * 1600 * 32 / 8 = 0xfa0000 bytes are needed.

+config SPL_CONSOLE_SCROLL_LINES

+	  for the display.

+config SPL_SPLASH_SCREEN_ALIGN
+	bool "Allow positioning the splash image anywhere on the display at SPL"
+	help
+	  If this option is set the splash image can be freely positioned
+	  on the screen only at SPL. Environment variable "splashpos" specifies
+	  the position as "x,y". If a positive number is given it is used as
+	  number of pixel from left/top. If a negative number is given it
+	  is used as number of pixel from right/bottom.
+
+config SPL_SPLASH_SOURCE
+	bool "Control the source of the splash image at SPL"
+	help
+	  Use the splash_source.c library. This library provides facilities to
+	  declare board specific splash image locations, routines for loading
+	  splash image from supported locations, and a way of controlling the
+	  selected splash location using the "splashsource" environment
+	  variable.
+
+	  This CONFIG works as follows:
+
+	  - If splashsource is set to a supported location name as defined by
+	    board code, use that splash location.
+	  - If splashsource is undefined, use the first splash location as
+	    default.
+	  - If splashsource is set to an unsupported value, do not load a splash
+	    screen.
+
+	  A splash source location can describe either storage with raw data, a
+	  storage formatted with a file system or a FIT image. In case of a
+	  filesystem, the splash screen data is loaded as a file. The name of
+	  the splash screen file can be controlled with the environment variable
+	  "splashfile".
+
+	  To enable loading the splash image from a FIT image, CONFIG_FIT must
+	  be enabled. The FIT image has to start at the 'offset' field address
+	  in the selected splash location. The name of splash image within the
+	  FIT shall be specified by the environment variable "splashfile".
+
+	  In case the environment variable "splashfile" is not defined the
+	  default name 'splash.bmp' will be used.
