Chenli Wei 635a6da1c0 hv:refine the min address logic of high memory ...

Current mmu assum the high memory start from 4G,it's not true for some
platform.

The map logic use "high64_max_ram - 4G" to calculate the high ram size
without any check,it's an issue when the platform have no high memory.

So this patch add high64_min_ram variable to calculate the min address
of high memory and check the high64_min_ram to fix the previou issue.
