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
