Subject: unicore32: stop printing the virtual memory layout

Since ad67b74d2469d9b8 ("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. 
071929dbdd865f77 ("arm64: Stop printing the virtual memory layout") and
31833332f7987636 ("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.
