Reduce fuse.c to the minimum functionality required for the early bootstages.
Also export tegra_read_straps() for use by the fuse driver.

Aha, but why?
-static void __init tegra20_fuse_init_randomness(void)

-
-       randomness[0] = tegra_fuse_readl(FUSE_UID_LOW);
-       randomness[1] = tegra_fuse_readl(FUSE_UID_HIGH);
-
-       add_device_randomness(randomness, sizeof(randomness));
-}

-/* Applies to Tegra30 or later */
-static void __init tegra30_fuse_init_randomness(void)
-{
-       u32 randomness[7];
-
-       randomness[0] = tegra_fuse_readl(FUSE_VENDOR_CODE);
-       randomness[1] = tegra_fuse_readl(FUSE_FAB_CODE);
-       randomness[2] = tegra_fuse_readl(FUSE_LOT_CODE_0);
-       randomness[3] = tegra_fuse_readl(FUSE_LOT_CODE_1);
-       randomness[4] = tegra_fuse_readl(FUSE_WAFER_ID);
-       randomness[5] = tegra_fuse_readl(FUSE_X_COORDINATE);
-       randomness[6] = tegra_fuse_readl(FUSE_Y_COORDINATE);
-
-       add_device_randomness(randomness, sizeof(randomness));

We still want to get this into the random pool right? Can it not simply
be moved to a later initcall then?
