ARM: OMAP: id: add chip id recognition for omap4430 es2.3
allow for the omap4430 es2.3 revision to be recognized in the omap4_check_revision() function. most aspects of all omap4430 es2.x versions are identical, however a number of small variations such as default pullup or pulldown resistor configurations vary between revisions. detailed information on silicon errata for omap4430 revisions can be found at http://focus.ti.com/pdfs/wtbu/swpz009D.pdf Signed-off-by: David Anders <x0132446@ti.com> Signed-off-by: Tony Lindgren <tony@atomide.com>
