unicore32: stop printing the virtual memory layout (1476ea25) · Commits · 戴 / test

Since commit ("printk: hash addresses printed with %p"), the virtual memory layout printed during boot up contains "ptrval" instead of actual addresses. Instead of changing the printing to "%px", and leaking virtual memory layout information again, just remove the printing completely, cfr. e.g. commits ("arm64: Stop printing the virtual memory layout") and ("m68k/mm: Stop printing the virtual memory layout"). All interesting information (actual section sizes) is already printed by mem_init_print_info() just above anyway.
