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] net: dsa: bcm_sf2: setup BCM4908 internal crossbar
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-On some SoCs (e.g. BCM4908, BCM631[345]8) SF2 has an integrated
-crossbar. It allows connecting its selected external ports to internal
-ports. It's used by vendors to handle custom Ethernet setups.
-
-BCM4908 has following 3x2 crossbar. On Asus GT-AC5300 rgmii is used for
-connecting external BCM53134S switch. GPHY4 is usually used for WAN
-port. More fancy devices use SerDes for 2.5 Gbps Ethernet.
-
-              ┌──────────┐
-SerDes ─── 0 ─┤          │
-              │   3x2    ├─ 0 ─── switch port 7
- GPHY4 ─── 1 ─┤          │
-              │ crossbar ├─ 1 ─── runner (accelerator)
- rgmii ─── 2 ─┤          │
-              └──────────┘
-
-Use setup data based on DT info to configure BCM4908's switch port 7.
-Right now only GPHY and rgmii variants are supported. Handling SerDes
-can be implemented later.
