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

Browse source

commit 3484de7bcb 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).
