hw/arm/integratorcp: Support specifying features via -cpu 

Since the integratorcp board creates the CPU object directly
rather than via cpu_arm_init(), we have to call the CPU
class parse_features() method ourselves if we want to
support the user passing features via the -cpu command
line argument as well as just the cpu name. Do so.
