omap3: Runtime detection of OMAP35x devices
Add runtime check for these OMAP35x variations based on the detected Si features: OMAP3503, OMAP3515, OMAP3525 and OMA3530. Also, delayed the call to pr_info() into actual variant is detected in omap3_cpuinfo() Signed-off-by: Sanjeev Premi <premi@ti.com> Signed-off-by: Tony Lindgren <tony@atomide.com>
