[PATCH] i2c: mv64xxx: Do not use writel_relaxed()

[Thierry Reding]

The driver is used on PowerPC which don't provide writel_relaxed(). This
breaks the c2k and prpmc2800 default configurations. To fix the build,
turn the calls to writel_relaxed() into writel(). The impacts for ARM
should be minimal.

Applied to for-current, thanks!
