[PATCH v2 1/5] hw/net:ftgmac100: update memory region size to 0x200

[Jamin Lin]

According to the datasheet of ASPEED SOCs,
one MAC controller owns 128KB of register space for AST2500.

However, one MAC controller only owns 64KB of register space for AST2600
and AST2700.

It set the memory region size 128KB and it occupied another
controllers Address Spaces.

Currently, the ftgmac100 model use 0x100 register space.
To support DMA 64 bits dram address and new future mode(ftgmac100_high) which
have "Normal Priority Transmit Ring Base Address Register High(0x17C)",
"High Priority Transmit Ring Base Address Register High(0x184)" and
"Receive Ring Base Address Register High(0x18C)" to save the high part physical
address of descriptor manager.

Update memory region size to 0x200.
