1.Add X1830 system type for cat /proc/cpuinfo to give out X1830. 2.Change "PRID_IMP_XBURST" to "PRID_IMP_XBURST_REV1" and add a new "PRID_IMP_XBURST_REV2" for new Ingenic CPUs which has XBurst with MXU2 SIMD ISA. Notice: 1."PRID_IMP_XBURST_REV2" is corresponds to the latest XBurst processor with 128bit MXU2 SIMD instruction set, not the upcoming XBurst2 processor. This version of the processors fixes issues such as BTB and HPTLB. 2.In order to simplify and reuse the code, the "c->cputype" and the "c->writecombine" and the "__cpu_name[cpu]" in the original "PRID_IMP_XBURST" (now is "PRID_IMP_XBURST_REV1") are removed, and the corresponding settings are abtained through fall-through to "PRID_IMP_XBURST_REV2", which will cause the name that was previously mistakenly called "JZRISC" to become to the real name "XBurst".
