[PATCH 1/3] ARM: SAMSUNG: Add the member of platdata to implement SDMMC Write Protection

[Kukjin Kim]

From: Lee Hyuk <hyuk1.lee at samsung.com>

This patch adds the members of platdata which are cfg_wp and get_ro.
The cfg_wp is the function for setting the specific GPIO for WP pin
and get_ro is the function for getting data from the assigned GPIO.
