mm: fix suspend crash on u200 [1/1]

PD#SWPL-1219

Problem:
When open vmap stack, suspend will fail on U200. If open cpu idle,
resume from idle will fail too.

Solution:
set up vmap stack early before open IRQ. If set up this stack late
than IRQ open, stack will point to a ramdom address

Verify:
u200
