MLK-19465 imx8mq: Fix cpu rev issue on B0.1 chip

We read the ROM version to determine the CPU revision before B1 chip.
The rom version is 4 bytes word, it has major version at low byte,
minor version at second byte.

On B0.1 chip, the value is 0x1020 not 0x20, if reading the word and
comparing
with 0x20, the result is wrong.

Fix the issue by only reading the lowest byte for major version.
