Blackfin arch: remove useless SSYNC() in irq priority code
- remove SSYNC() left over from irq init split - do not force SSYNC() when masking/unmasking IRQs in the SIC as any order enforced by the hardware should already be enforced by software Signed-off-by: Mike Frysinger <vapier.adi@gmail.com> Signed-off-by: Bryan Wu <cooloney@kernel.org>
