Salman Nabi 1c08ff3277 feat(arm): add initrd props to dtb at build time
Add initrd properties to the device tree blob at build time, giving
users the ability to run a linux kernel and successfully boot it to
the terminal. Users can boot a linux kernel in a normal flow as well
as in RESET_TO_BL31. This function is an extension of the build time
option "ARM_LINUX_KERNEL_AS_BL33=1".

The build time options INITRD_SIZE or INITRD_PATH will trigger the
insertion of initrd properties in to the DTB. If both options are
provided then the INITRD_SIZE will take precedence.

The available options are:
INITRD_SIZE: Provide the initrd size in dec or hex (hex format must
precede with '0x'.
Example: INITRD_SIZE=0x1000000

INITRD_PATH: Provide an initrd path for the build time to find its
exact size.

INITRD_BASE: A required build time option that sets the initrd base
address in hex format. A default value can be set by the platform.
Example: INITRD_BASE=0x90000000
