Revert "pm: Remove CURRENT_CPU macro"

[kv2019i]

This reverts commit b9d4b9d.

System resume fails every time with this patch on Intel ACE ADSP platform. Initial boot is ok, but system resume fails.

i have seen some issues with this as well, lets revert and come up with a working fix.

[kv2019i]

@ceolin I added some debug to the build and the

void pm_system_resume(void)
{
»       uint8_t id = CURRENT_CPU;
»       printk("DEBUG: id %d, z_smp_cpu_mobile:%d arch cpu %u\n", id, z_smp_cpu_mobile(), arch_curr_cpu());

Gives me

DEBUG: id 0, z_smp_cpu_mobile:1 arch cpu 1074840120

So it's the kernel_structs.h assert that fires:

#define _current_cpu ({ __ASSERT_NO_MSG(!z_smp_cpu_mobile()); \
»       »       »       arch_curr_cpu(); })

@nashif @kv2019i this is the proper fix #67863

That change just exposed an existent problem.

@ceolin Confirmed #67863 fixes the issue, closing this revert as that one seems to be close to merge.
