memblock is now fully integrated into the kernel and is the prefered
method for tracking memory. Rather than reinvent the wheel with
meminfo, migrate to using memblock directly instead of meminfo as
an intermediate.

So, I also just noticed that you specifically remove the call to
sharpsl_save_param() here.  I'm presuming that this is also an error, as
you haven't removed it from any of the other pxa fixups, and it seems
unrelated to the change.

With the changes to this function, I think you can outright remove
early_init_dt_add_memory_arch() from arch/arm/kernel/devtree.c. The
default implementation (__weak) in drivers/of/fdt.c uses memblock
directly.

This patch fails with SPARSEMEM enabled (tested with v3.14-rc1, 
exynos4_defconfig + oldnoconfig):
