kernel: delete Linux 5.4 config and patches

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] PCI: mobiveil: Make mobiveil_host_init() can be used to
- re-init host
-
-Make the mobiveil_host_init() function can be used to re-init
-host controller's PAB and GPEX CSR register block, as NXP
-integrated Mobiveil IP has to reset and then re-init the PAB
-and GPEX CSR registers upon hot-reset.
