qemu: Accessing UART1 causes a data abort

The register address range of UART1 (crash console) are outside the
address ranges mapped for MMIO, resulting to an MMU abort when the
device registers are accessed.

Increase the size of DEVICE1 memory to include the range of UART1.

Fixes ARM-software/tf-issues#560
