soc: sunxi: sram: add entry for a523

Browse Source 
The A523 has two Ethernet controllers. So in the system controller
address space, there are two registers for Ethernet clock delays,
one for each controller.

Add a new entry for the A523 system controller that allows access to
the second register.
