[ARM/tegra] suspend: remove literals from CPU save & restore code
use the ARMv7 movw and movt instructions to load literal values, rather
than allowing the compiler to silently generate literal sections all over
memory
since this code needs to be relocatable (may run with no MMU, may run
with MMU, may run in IRAM), the fewer literals, the better
