fix(BLE): MAX32690 DATC Hardfaulting with ICC enabled

[EricB-ADI]

Description

• Disabled ICC altogether on MAX32690 EvKits Hardfaults were occuring at AppTerminalInit. Seemingly due to timing.
• With optimizations turned off in int main(), hardfaults went away.
• Trace level 0 and trace level 2 had no hardfaults, only trace 1.
• Adding an instruction sync barrier caused the following to happen, which lead to believing cache is the issue.

  terminal: init
  terminal: init
  terminal: init
  terminal: init

  HardFault_Handler

Disabling cache around the init code, resolved the issue. This is a band aid fix and so It will just be disabled altogether.
