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] ASoC: fsl_sai: handle slave mode per TX/RX direction
-
-The SAI interface can be a clock supplier or consummer
-as function of stream direction, ie when interacting
-with I2S XTOR. Removed FSL_SAI_RFR define as it is now
-referred as FSL_SAI_RFR0.
