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] net: phy: at803x: fix probe error if copper page is selected
-
-The commit c329e5afb42f ("net: phy: at803x: select correct page on
-config init") selects the copper page during probe. This fails if the
-copper page was already selected. In this case, the value of the copper
-page (which is 1) is propagated through phy_restore_page() and is
-finally returned for at803x_probe(). Fix it, by just using the
-at803x_page_write() directly.
-
-Also in case of an error, the regulator is not disabled and leads to a
-WARN_ON() when the probe fails. This couldn't happen before, because
-at803x_parse_dt() was the last call in at803x_probe(). It is hard to
-see, that the parse_dt() actually enables the regulator. Thus move the
-regulator_enable() to the probe function and undo it in case of an
-error.
