ARM: l2c: add automatic enable of early BRESP
The AXI bus protocol requires that a write response should only be sent back to the master when the last write has been accepted. Early BRESP allows the L2C-310 to send the write response as soon as the store buffer accepts the write address. Cortex-A9 processors can signal to the L2C-310 that they wish to be notified early, and if this optimisation is enabled, the L2C-310 can signal an early write response.
