A lot of patches are outdated versions of upstreamed patches and drivers. So lets pull in the upstreamed patches and reorder remaining ones. This drops the unnecessary 721-dts-ipq4019-add-ethernet-essedma-node.patch which adds nodes for not yet in OpenWrt IPQESS driver.

Subject: [PATCH 03/11] crypto: qce - fix xts-aes-qce key sizes
|
|
|
|
XTS-mode uses two keys, so the keysizes should be doubled in
|
|
skcipher_def, and halved when checking if it is AES-128/192/256.
