ARM: dts: msm: Update USB QMP PHY register address size on msm8953

Currently used USB QMP PHY register address space size is 0x45c which is
used by Linux USB QMP PHY driver to memory mapped the region. Some of
QMP PHY registers' read/write offset is above this size. Hence increase
USB QMP PHY register address space size to 0x9f8 to memory map complete
USB QMP PHY related register address space.
