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 1/2] net: dsa: bcm_sf2: add function finding RGMII register
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-Simple macro like REG_RGMII_CNTRL_P() is insufficient as:
-1. It doesn't validate port argument
-2. It doesn't support chipsets with non-lineral RGMII regs layout
-
-Missing port validation could result in getting register offset from out
-of array. Random memory -> random offset -> random reads/writes. It
-affected e.g. BCM4908 for REG_RGMII_CNTRL_P(7).
-
-Fixes: a78e86ed586d ("net: dsa: bcm_sf2: Prepare for different register layouts")
