This patch provides an API to allow users to output multi-line
messages using VGA framebuffer.
The current limitation with multiline message is that,
vga_line_write() function is unable to understand newline character
hence, eventually output multiple lines separated with a newline
character with a single line statement.
This patch ensures to parse the entire string and split it into
multiple lines based on the newline character and print each line
separately to the VFG framebuffer.
User can choose to align the output video message as per given choice
between left/center/right of the screen
(i.e. enum VGA_TEXT_ALIGNMENT ).
Additionally, added macros to define the horizontal screen alignment
as well. Ideally if user would like to print the video message at the
middle of the screen then the vertical alignment would be
`VGA_TEXT_CENTER` and horizontal alignment would be
`VGA_TEXT_HORIZONTAL_MIDDLE`.
TEST=Able to build and boot Google/Taeko.

To deprecate VBOOT_VBNV_CMOS [1], replace VBOOT_VBNV_CMOS with

Currently BOOT_DEVICE_SPI_FLASH_NO_EARLY_WRITES is selected for

there seems to be no particular reason on those platforms. We've dropped
