[Impact]
The work-around for the Qualcomm Datacenter Technologies QDF2400 erratum 44 sets the qdf2400_e44_present" global variable if the work-around is needed. However, this check does not happen until after earlycon is initialized, which means the work-around is not used, and the console hangs as soon as it displays one character.

[Test Case]
Enable earlycon and boot the kernel.

[Regression Potential]
This impacts only Qualcomm Datacenter Technologies QDF2400 platforms.
