tools: cell-linux: arm: Do not page align the ramdisk size

When updating linux initrd size in inmate DT, the size is aligned
to page. Because of this some initrd images were not able to mount
by inmate as Linux is seeing junk at end of specified initrd.
Pass the exact initrd size to the Linux kernel.
