hw/arm/allwinner-h3: add SDRAM controller device

Browse source 
In the Allwinner H3 SoC the SDRAM controller is responsible
for interfacing with the external Synchronous Dynamic Random
Access Memory (SDRAM). Types of memory that the SDRAM controller
supports are DDR2/DDR3 and capacities of up to 2GiB. This commit
adds emulation support of the Allwinner H3 SDRAM controller.
