mediatek/mt8173: memlayout: Create DRAM DMA region for NOR flash DMA read.

NOR flash has a hardware limitation that it can't access SRAM region
    after 4GB mode is enabled. We add a DRAM DMA region after 0x40000000
    for NOR flash driver. So that the NOR flash driver can use this region
    after 4GB mode is enabled.

BRANCH=none
    BUG=chormoe-os-partner:49229
    TEST=Boot to kernel on rev4 w/ 2GB ram and rev3 w/ 4GB ram.
         And check /proc/meminfo.
