    arm64: memory: rename VA_START to PAGE_END · 77ad4ce6

    Prior to commit:
    
      14c127c9 ("arm64: mm: Flip kernel VA space")
    
    ... VA_START described the start of the TTBR1 address space for a given
    VA size described by VA_BITS, where all kernel mappings began.
    
    Since that commit, VA_START described a portion midway through the
    address space, where the linear map ends and other kernel mappings
    begin.
    
    To avoid confusion, let's rename VA_START to PAGE_END, making it clear
    that it's not the start of the TTBR1 address space and implying that
    it's related to PAGE_OFFSET. Comments and other mnemonics are updated
    accordingly, along with a typo fix in the decription of VMEMMAP_SIZE.
    
    There should be no functional change as a result of this patch.
