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 01/12] net: thunderx: use proper interface type for RGMII
-
-The configuration of the OCTEONTX XCV_DLL_CTL register via
-xcv_init_hw() is such that the RGMII RX delay is bypassed
-leaving the RGMII TX delay enabled in the MAC:
-
-	/* Configure DLL - enable or bypass
-	 * TX no bypass, RX bypass
-	 */
-	cfg = readq_relaxed(xcv->reg_base + XCV_DLL_CTL);
-	cfg &= ~0xFF03;
-	cfg |= CLKRX_BYP;
-	writeq_relaxed(cfg, xcv->reg_base + XCV_DLL_CTL);
-
-This would coorespond to a interface type of PHY_INTERFACE_MODE_RGMII_RXID
-and not PHY_INTERFACE_MODE_RGMII.
-
-Fixing this allows RGMII PHY drivers to do the right thing (enable
-RX delay in the PHY) instead of erroneously enabling both delays in the
-PHY.
