renesas-ra: Add a macro definition to avoid compile error of FSP v4.4.0. 

FSP v4.4.0 refers to CMSIS V5.4.1, and __COMPILER_BARRIER() is used in bsp.
On the other hand, lib/cmsis is V5.1.0 and the macro is not defined.
Therefore, compile error happens.
As the workaround, the macro definition is added.
If lib/cmsis is updated in the future, this addition can be removed.
