ARM: keystone2: add support for UART download 

Currently to flash u-boot image onto NAND or SPI NOR flash, very first
time user need to use Code Composer Studio (CCS). This is cumbersome for
an user not familiar with CCS. This patch add simpler procedure using
uart boot mode for K2 EVMs.

When UART bootmode is set and board is rebooted, the ROM boot loader
transfers the image at the beginning of the internal RAM. After the
transfer is complete the boot-loader sets the PC to the first internal RAM
address 0x0c000000. The u-boot.bin is linked to the address 0x0c001000.

In order to use the u-boot.bin as an image for UART download, we need to
add 4K zeros prefix that act as 1K NOP instructions before reaching
0xc001000.
