s3cmci-dont-leak-pdata.patch

When compiling s3cmci as a module and doing an insmod-rmmod-insmod
sequence, s3cmci_probe often oopses because the platform data contains
garbage.

The reason for this is that I'm not providing any platform data (removed
in gta02-mmc-mci.patch), and thus s3cmci tries to put its own defaults:

        if (!host->pdata) {
                pdev->dev.platform_data = &s3cmci_def_pdata;
                host->pdata = &s3cmci_def_pdata;
        }

s3cmci_def_pdata is inside the module, so the pointer in
pdev->dev.platform_data becomes invalid after the module is unloaded.

Since nothing else in s3cmci uses pdev->dev.platform_data, "patching"
it seems unnecessary. This patch removes it.
