Based on CPU type choose generic omap3 or omap3430 specific cpuidle
parameters. Parameters for omap3430 were measured on Nokia N900 device and
added by commit 5a1b1d3a ("OMAP3: RX-51: Pass cpu idle parameters")
which were later removed by commit 231900af ("ARM: OMAP3: cpuidle -
remove rx51 cpuidle parameters table") due to huge code complexity.

This patch brings cpuidle parameters for omap3430 devices again, but uses
simple condition based on CPU type.

Fixes: 231900af ("ARM: OMAP3: cpuidle - remove rx51 cpuidle
parameters table")
