[TF-M] fce78aef breaks psoc64 console output with IARARM and ARMCLANG toolchain

The current version breaks console output for the secure partition on psoc64 with IAR or ARMCLANG. Appears to work with GNUARM.

It appears that this commit is the culprit: fce78aef  Platform: Duplicate the tfm_hal_platform_init

The console starts out good, then during tests only garbage is seen.

Linker script issues?
