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 4/7] bcm63xx_enet: alloc rx skb with NET_IP_ALIGN
-
-Use netdev_alloc_skb_ip_align on newer SoCs with integrated switch
-(enetsw) when refilling RX. Increases packet processing performance
-by 30% (with netif_receive_skb_list).
-
-Non-enetsw SoCs cannot function with the extra pad so continue to use
-the regular netdev_alloc_skb.
-
-Tested on BCM6328 320 MHz and iperf3 -M 512 to measure packet/sec
-performance.
-
-Before:
-[ ID] Interval Transfer Bandwidth Retr
-[ 4] 0.00-30.00 sec 120 MBytes 33.7 Mbits/sec 277 sender
-[ 4] 0.00-30.00 sec 120 MBytes 33.5 Mbits/sec receiver
-
-After (+netif_receive_skb_list):
-[ 4] 0.00-30.00 sec 155 MBytes 43.3 Mbits/sec 354 sender
-[ 4] 0.00-30.00 sec 154 MBytes 43.1 Mbits/sec receiver
