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A lot of patches are outdated versions of upstreamed patches and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.

+ driver
+
+This introduces the IPQ4019 VQMMC LDO driver needed for
+the SD/EMMC driver I/O level operation.
+This will enable introducing SD/EMMC support for the built-in controller.
