arm64: update stale PAGE_OFFSET comment
Commit ab893fb9f1b17f02 ("arm64: introduce KIMAGE_VADDR as the virtual
base of the kernel region") logically split KIMAGE_VADDR from
PAGE_OFFSET, and since commit f9040773b7bbbd9e ("arm64: move kernel
image to base of vmalloc area") the two have been distinct values.
Unfortunately, neither commit updated the comment above these
definitions, which now erroneously states that PAGE_OFFSET is the start
of the kernel image rather than the start of the linear mapping.
This patch fixes said comment, and introduces an explanation of
KIMAGE_VADDR.
