m68k/mm: Stop printing the virtual memory layout

m68k/mm: Stop printing the virtual memory layout

Since commit ad67b74d2469d9b8 ("printk: hash addresses printed with
%p"), the virtual memory layout printed during boot up contains "ptrval"
instead of actual addresses:

    Memory: 268040K/276480K available (2979K kernel code, 310K rwdata, 784K rodata, 144K init, 172K bss, 8440K reserved, 0K cma-reserved)
    Virtual kernel memory layout:
	vector  : 0x003d2e74 - 0x003d3274   (   1 KiB)
	kmap    : 0xd0000000 - 0xf0000000   ( 512 MiB)
	vmalloc : 0x11800000 - 0xd0000000   (3048 MiB)
	lowmem  : 0x00000000 - 0x11000000   ( 272 MiB)
	  .init : 0x(ptrval) - 0x(ptrval)   ( 144 KiB)
	  .text : 0x(ptrval) - 0x(ptrval)   (2980 KiB)
	  .data : 0x(ptrval) - 0x(ptrval)   (1095 KiB)
	  .bss  : 0x(ptrval) - 0x(ptrval)   ( 173 KiB)

Instead of changing the printing to "%px", and leaking virtual memory
layout information again, just remove the printing completely, cfr. e.g.
commit 071929dbdd865f77 ("arm64: Stop printing the virtual memory
layout").

All interesting information (actual section sizes) is already printed by
mem_init_print_info() just above anyway.
