[PATCH 1/1] PLAT: OMAP: Add device configuration to support second HSMMC slot on OMAP 2430 and 3430 boards.

[Carlos Aguiar <carlos.aguiar@indt.org.br>]

From: Jarkko Lavinen <jarkko.lavinen@nokia.com>

This patch adds device configuration to provide second HSMMC slot support
on OMAP 2430 and 3430 boards.

Signed-off-by: Jarkko Lavinen <jarkko.lavinen@nokia.com>

Change CONFIG_ARCH_OMAP24XX by CONFIG_ARCH_OMAP243X macro when this config
is needed only for 2430 boards.
