hw/arm/bcm2835: Use object_initialize() on PL011State

To be coherent with the other peripherals contained in the
BCM2835PeripheralState structure, directly allocate the PL011State
(instead of using the pl011 uart as a pointer to a SysBusDevice).

Initialize the PL011State with object_initialize() instead of
object_new().
