[PATCH] drm/exynos/gem: Fix printk specifier for gem_object.size and dma_addr

[Chen-Yu Tsai <wenst@chromium.org>]

In the recent change to use the GEM base object's size field instead of
the exynos_gem object's additional field, the printk format was not
adjusted for the change to size_t type. This causes a new warning on
platforms on which size_t is not unsigned long.

Fix this by using the correct "%zx" type.

While at it, fix the specifier for dma_addr so that the cast to unsigned
long is not longer needed.

This is only compile tested. Build for ARM 32-bit confirms the warning
is fixed. Sorry for the noise.
