ARM: dts: Fix cm2 and prm sizes for omap4

BugLink: http://bugs.launchpad.net/bugs/1794889
[ Upstream commit bc8a3ef1940c9a6dfa316b31e063fdd4fbab0add ]

The size of these modules is 0x2000, not 0x3000. The extra 0x1000
after 0x2000 is for the interconnect target agent which is a separate
device.

control module support")
