The size of device tree node secmon (bl31_secmon_reserved) was
incorrect. It should be increased to 2MiB (0x200000).
The origin setting will cause some abnormal behavior due to
trusted-firmware-a and related firmware didn't load correctly.
The incorrect behavior may vary because of different software stacks.
For example, it will cause build error in some Yocto project because
it will check if there was enough memory to load trusted-firmware-a
to the reserved memory.
