[ARM] 4133/1: Add ISB after changes to CP15 registers

According to ARM ARM, changes to the CP15 registers are only
guaranteed to be visible after an Instruction Synchronization Barrier
(ISB). This patch adds the ISB at the end of set_cr and
set_copro_access functions and also moves them further down in the
file, below the isb macro definition.
