This patch fixes a compiler warning in gemini_restart()
issued by commit 7b6d864b ("reboot:arm: reboot_mode
changes from char to enum reboot_mode").

arch/arm/mach-gemini/board-rut1xx.c:93:2: warning: initialization from incompatible pointer type

The warning is harmless, and the patch does not need to
be backported to stable kernels.

Fixes: 7b6d864b ("reboot:arm: reboot_mode changes from char to enum reboot_mode.")

There is no defconfig file for gemini, which has lead to a lot
of bitrot. This makes the broken board files, the gpio implementation
and the reset logic work again, and fixes the build warnings
that got introduced with the changes to the readl/writel prototypes.
