hw/arm/bcm2836: Use ARM_CPU 'mp-affinity' property

The 'mp-affinity' property is present since commit 15a21fe028
("target-arm: Add mp-affinity property for ARM CPU class").
Use it and remove a /* TODO */ comment. Since all ARM CPUs
have this property, use &error_abort, because this call can
not fail.
