Repair Ingenic SoCs L2 cache capacity detection.

[周琰杰 (Zhou Yanjie)]

1.The X1000E SoC has a 4-way L2 cache with a capacity of 128 KiB.
  The current code cannot detect its correctly, which will cause the
  CU1000-Neo board using the X1000E SoC to report that it has found
  a 5-way 320KiB L2 cache at boot time.
2.The JZ4775 SoC has a 4-way L2 cache with a capacity of 256 KiB.
  The current code cannot detect its correctly, which will cause the
  Mensa board using the JZ4775 SoC to report that it has found a 5-way
  320KiB L2 cache at boot time.

This series of patches is to fix this problem.
