arm64: Split pr_notice("Virtual kernel memory layout...") into multiple pr_cont()
The printk() implementation has a limit of LOG_LINE_MAX (== 1024 - 32)
buffer per call which the arm64 mem_init() breaches when printing the
virtual memory layout with CONFIG_KASAN enabled. The result is that the
last line is no longer printed. This patch splits the call into a
pr_notice() + additional pr_cont() calls.
