Peter De Schrijver 35874f3617 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 a7cbe92cef ("ARM: tegra: remove tegra EMC scaling
driver").
