kernel: remove support for kernel 4.19

We use 5.4 on all targets by default, and 4.19 has never been released
in a stable version. There is no reason to keep it.

-Subject: [PATCH] dt-bindings: dmaengine: dw-dmac: add protection control
- property
-
-This patch for the DesignWare AHB Central
-Direct Memory Access Controller adds the dma
-protection control property:
-	"snps,dma-protection-control"
-
-as well as the properties specific values defines into
-a new include file: include/dt-bindings/dma/dw-dmac.h
-
-Note: The protection control signals are one-to-one
-mapped to the AHB HPROT[1:3] signals for this controller.
-The HPROT0 (Data Access) is always hardwired to 1.

-Subject: [PATCH 03/15] crypto: drop mask=CRYPTO_ALG_ASYNC from 'cipher' tfm
- allocations
-
-'cipher' algorithms (single block ciphers) are always synchronous, so
-passing CRYPTO_ALG_ASYNC in the mask to crypto_alloc_cipher() has no
-effect.  Many users therefore already don't pass it, but some still do.
-This inconsistency can cause confusion, especially since the way the
-'mask' argument works is somewhat counterintuitive.
-
-Thus, just remove the unneeded CRYPTO_ALG_ASYNC flags.
-
-This patch shouldn't change any actual behavior.

-Subject: [PATCH 04/15] crypto4xx_core: don't abuse __dma_sync_page
-
-This function is internal to the DMA API implementation. Instead use
-the DMA API to properly unmap. Note that the DMA API usage in this
-driver is a disaster and urgently needs some work - it is missing all
-the unmaps, seems to do a secondary map where it looks like it should
-to a unmap in one place to work around cache coherency and the
-directions passed in seem to be partially wrong.

-Subject: [PATCH 06/15] crypto: crypto4xx - add prng crypto support
-
-This patch adds support for crypto4xx's ANSI X9.17 Annex C compliant
-pseudo random number generator which provides a pseudo random source
-for the purpose of generating  Initialization Vectors (IV's) for AES
-algorithms to the Packet Engine and other pseudo random number
-requirements.

-Subject: [PATCH] usb: xhci: add firmware loader for uPD720201 and uPD720202
- w/o ROM
-
-This patch adds a firmware loader for the uPD720201K8-711-BAC-A
-and uPD720202K8-711-BAA-A variant. Both of these chips are listed
-in Renesas' R19UH0078EJ0500 Rev.5.00 "User's Manual: Hardware" as
-devices which need the firmware loader on page 2 in order to
-work as they "do not support the External ROM".
-
-The "Firmware Download Sequence" is describe in chapter
-"7.1 FW Download Interface" R19UH0078EJ0500 Rev.5.00 page 131.
-
-The firmware "K2013080.mem" is available from a USB3.0 Host to
-PCIe Adapter (PP2U-E card) "Firmware download" archive. An
-alternative version can be sourced from Netgear's WNDR4700 GPL
-archives.
-
-The release notes of the PP2U-E's "Firmware Download" ver 2.0.1.3
-(2012-06-15) state that the firmware is for the following devices:
- - uPD720201 ES 2.0 sample whose revision ID is 2.
- - uPD720201 ES 2.1 sample & CS sample & Mass product, ID is 3.
- - uPD720202 ES 2.0 sample & CS sample & Mass product, ID is 2.
-
-If someone from Renesas is listening: It would be great, if these
-firmwares could be added to linux-firmware.git.
