kernel: delete Linux 5.4 config and patches

As the upcoming release will be based on Linux 5.10 only, remove all

There were no targets still actively using Linux 5.4.

-Subject: [PATCH] staging/fsl_qbman: stop using current_kernel_time()
-
-The current_kernel_time() call was removed in [1] in order to avoid
-overflows in 2038. Use ktime_get_coarse_real_ts64() instead.
