This adds a define for the bit in rstmgr's ctrl regiser that issues a cold reset (we had a define for the warm reset bit only) in preparation for a proper sysrese driver. Signed-off-by: Simon Goldschmidt <simon.k.r.goldschmidt@gmail.com> Series changes: 2 - separate this patch to the register descriptions from the actual sysreset driver patch
