BUILD: Update For IAR support

Browse Source 
Applied the same change as in mbed-crypto for using this as a sub
project with the IAR toolchain. Use __asm generic ,and avoid empty
enum. Avoid declaration of array with null size. This is a porting
of the original patch contributed to trusted-firmware-m.
