As the upcoming release will be based on Linux 5.10 only, remove all
kernel configuration as well as patches for Linux 5.4.
There were no targets still actively using Linux 5.4.

-Subject: [PATCH] irqchip/qeic: merge qeic_of_init into qe_ic_init
-
-qeic_of_init just get device_node of qeic from dtb and call qe_ic_init,
-pass the device_node to qe_ic_init.
-So merge qeic_of_init into qe_ic_init to get the qeic node in
-qe_ic_init.
