We don't care E bit of SVR in most cases. Clear E bit for SVR_SOC_VER(). This will simplify the coding. Use IS_E_PROCESSOR() to identify SoC with encryption. Remove all _E entries from SVR list and CPU list.

Erratum NMG_CPU_A011 applies to P4080 rev 1.0, 2.0, fixed in rev 3.0. It also applies to P3041 rev 1.0, 1.1, P2041 rev 1.0, 1.1. It shares the same workaround as erratum CPU22. Rearrange registers usage in assembly code to avoid accidental overwriting.
