imx8ulp_evk: Fix ELE FW version print bug

According to latest ELE Get FW version API, the FW version word is defined
as below. The patch version only has 4 bits and minor version has 12 bits.
However, the codes use 8 bits for patch version and minor version. Add the
patch to fix the issue.

ELE firmware version
[31] - When set indicates a dirty build.
[30] - Reserved
[29:28] - Hotfix version.
[27] - When set, indicate that ELE FW is authenticated and operational.
[26:25] - Reserved
[24] - When set, indicate that an alternative FW is running.
[23:16] - Indicate the major version. This byte is checked against the
version set in the fuses to determine if the FW execution can be authorized
[15:4] - Indicate the minor version.
[3:0] - Indicate the patch version.
