[target]: Add code to use splash image as a character array

Represent the splash image in the form of a character array.
Use this array instead of reading the splash image from nand device.
Reduce the debug messages that are displayed on the screen.

The time taken by the bootloader is reduced by ~325ms with this change on
a MDDI display device.

Below are the steps/commands to convert the splash image into a character array:
1. $convert -depth 8 <splash image in PNG format> rgb:splash.raw
2. $host/linux-x86/bin/rgb2565 < ./splash.raw > final.img
3. $hexdump -C -v final.img | tr -s " " | cut -d ' ' -f2-17 | awk 'BEGIN {print "{"}
                {OFS=""; ORS=""; print "\t"; for(i=1; i <= NF; i++) print "0x"$i", "; print "\n";}
                END {print "}\n"}' > array.txt
