core: arm: psci: add suspend resume common functions

Add cpu suspend/resume common functions.

Platform psci suspend functions need to call
sm_pm_cpu_suspend(arg, platform_suspend) to runs into suspend.

The i.MX flow is:
psci_cpu_suspend->imx7_cpu_suspend->sm_pm_cpu_suspend(arg, func)
The "func" runs in on-chip ram that not losing power when
system runs into suspend or low power state. Argument "arg" is
passed to function "func" as argument through register "r0".

Pass non-secure context to psci functions. When cpu/system suspends,
cpu may loose power, so when back to linux from tee, tee
needs to return to a linux resume point, not the usual return address
after "smc" instruction. So we need to modify the mon_lr
value in non-secure context.

Psci runs in monitor mode, sm_get_nsec_ctx can not be used,
so pass the non-secure context pointer to the psci suspend function.

Adds

which translates from mpdir to core position, like get_core_pos() does
for the calling core.

get_core_pos_mpidr() a weak function to
allow platforms to override the implementation.

get_core_pos() now uses get_core_pos_mpidr() internally to calculate the
core position without using any stack.

With get_core_pos_mpidr() all the platform specific implementations of
get_core_pos() has been replaced with get_core_pos_mpidr() and
get_core_pos() is not weak any longer to avoid unexpected runtime errors
in out of tree rebased platforms.

core: make panic call stack consistent with abort call stack

The call stack is formatted differently when the TEE code panics vs.
when it receives an abort exception. The unfortunate consequence is,
the symbolize.py helper script cannot be used to troubleshoot panics.

Fix the issue by introducing common functions to format the call stack:
print_call_stack_arm32() and print_call_stack_arm64(), and by using
them in the panic and abort paths.
