[PATCH] ARM: mach-shmobile: ap4evb: fix write protect for SDHI1

[Arnd Hannemann]

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.
