bsps/powerpc: Add PPC_EXC_CONFIG_USE_FIXED_HANDLER
In case a BSP enables this option, then fixed high level exception
handler will be used. For normal asynchronous exceptions this is
bsp_interrupt_dispatch() and for other exceptions this is the handler
from the read-only ppc_exc_handler_table. The global handler is
C_exception_handler(). This avoids some dependencies on valid
read-write data.
