kernel: smp: change back the order of SMP thread and timer initialization
Commit 3457118 changed the sequence of z_smp_thread_init() and
smp_timer_init() in smp_init_top() subroutine, which initializes
other BPs. In some boards (up_squared, acrn_ehl_crb) it will fail to
work while SMP enabling. If the timer interrupt is enabled before the
first thread was initialized. Now change back to its original order.
Fixes #41835
