ARM: tegra: move fuse exports to soc/tegra/fuse.h
All fuse related functionality will move to a driver in the following patches. To prepare for this, export all the required functionality in a global header file and move all users of fuse.h to soc/tegra/fuse.h. While we're at it, remove tegra_bct_strapping, as its only user was removed in Commit a7cbe92cef27 ("ARM: tegra: remove tegra EMC scaling driver").
