sunxi: change SUNXI_HIGH_SRAM option to SUNXI_SRAM_ADDRESS
The new Allwinner H6 SoC has its SRAM A1 at neither 0x0 nor 0x10000, but
it's at 0x20000. Thus the SUNXI_HIGH_SRAM option needs to be refactored
to support this new configuration.
Change it to SUNXI_SRAM_ADDRESS, which holds the real address of SRAM
A1 in the memory map.
