fix(plat/mediatek/mt8195): extend MMU region size
In mt8195 suspend/resume flow, ATF has to communicate with a subsys by
read/write the subsys registers. However, the register region of subsys
doesn't include in the MMU mapping region. It triggers MMU faults.
This patch extends the MMU region 0 size to cover all mt8195 HW modules.
This patch also remove MMU region 1 because region 0 covers region 1.
