ARM: dts: Fix up SQ201 flash access

BugLink: https://bugs.launchpad.net/bugs/1855787
[ Upstream commit d88b11ef91b15d0af9c0676cbf4f441a0dff0c56 ]

This sets the partition information on the SQ201 to be read
out from the RedBoot partition table, removes the static
partition table and sets our boot options to mount root from
/dev/mtdblock2 where the squashfs+JFFS2 resides.
