ARM: move FSR fault status definitions before fsr_fs()
The FSR's fault status bits depend on whether LPAE is enabled. Rather
than always exposing both LPAE and non-LPAE to all code, move them
inside the ifdef blocks dependent on LPAE to restrict their visibility.
No code other than fsr_fs() makes use of these.
