ipq40xx: 5.4: update and reorder patches

A lot of patches are outdated versions of upstreamed patches and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 11/11] crypto: qce - handle AES-XTS cases that qce fails
+
+QCE hangs when presented with an AES-XTS request whose length is larger
+than QCE_SECTOR_SIZE (512-bytes), and is not a multiple of it.  Let the
+fallback cipher handle them.
