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] can: flexcan: rename struct
- flexcan_priv::reg_imask{1,2}_default to rx_mask{1,2}
-
-The flexcan IP core has up to 64 mailboxes, each one has a corresponding
-interrupt bit in the iflag1 or iflag2 registers and a mask bit in the
-imask1 or imask2 registers.
-
-In the timestamp (i.e. non FIFO) mode the driver needs to mask out all
-non RX interrupt sources and uses the precomputed values
-reg_imask1_default and reg_imask2_default of struct flexcan_priv for
-this.
-
-However in the current driver the reg_imask{1,2}_default cannot be used
-directly to get the pending RX interrupts. The TX interrupt is part of
-these variables, so it needs to be masked out, too.
-
-This is a preparation patch to clean up calculation of the pending RX
-interrupts, it only renames the variables from
-
-    reg_imask{1,2}_default
-
-to
-
-    rx_mask{1,2}
-
-To better reflect their meaning after the complete conversion. This
-change is done with the following sed command:
-
-    sed -i -e "s/reg_imask\(1\|2\)_default/rx_mask\1/" drivers/net/can/flexcan.c
