Subject: MIPS: Loongson-3: Reserve 32MB for RS780E integrated GPU

From: Huacai Chen <[email protected]>

commit 3484de7bcbed20ecbf2b8d80671619e7059e2dd7 upstream.

Due to datasheet, reserving 0xff800000~0xffffffff (8MB below 4GB) is not enough for RS780E integrated GPU's TOM (top of memory) registers and MSI/MSI-x memory region, so we reserve 0xfe000000~0xffffffff (32MB below 4GB).
