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] soc: fsl: handle RCPM errata A-008646 on SoC LS1021A
-
-Description:
-	- Reading configuration register RCPM_IPPDEXPCR1
-	  always return zero
-
-Workaround:
-	- Save register RCPM_IPPDEXPCR1's value to
-	  register SCFG_SPARECR8.(uboot's psci also
-	  need reading value from the register SCFG_SPARECR8
-	  to set register RCPM_IPPDEXPCR1)
-
-Impact:
-	- FlexTimer module will cannot wakeup system in
-	  deep sleep on SoC LS1021A
