generic: 6.6: fix uncompressed kallsyms

Currently, the existing uncompressed kallsym support is causing qualcommax
boards to hang on boot, and only after earlycon and verbose BUG() prints
are enabled the trace is visible:
[    0.000000] ------------[ cut here ]------------
[    0.000000] kernel BUG at kernel/kallsyms.c:340!
[    0.000000] Internal error: Oops - BUG: 00000000f2000800 [#1] SMP

Felix has fixed up the uncompressed kallsyms support so modify the current
patch with the fix.
All credits for the code go to Felix.
