PATCH 1/1 ARM: mach-shmobile: ap4evb: fix write protect for SDHI1

SDHI1 on AP4EVB has no pin to detect write protection of a card. This had the result that a card inserted in this slot was always detected as read only. This patch adds the corresponding flag to disable write protection detection for SDHI1.
