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A lot of patches are outdated versions of upstreamed patches and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 2/2] clk: fix apss cpu overclocking
-
-There's an interaction issue between the clk changes:"
-clk: qcom: ipq4019: Add the apss cpu pll divider clock node
-clk: qcom: ipq4019: remove fixed clocks and add pll clocks
-" and the cpufreq-dt.
-
-cpufreq-dt is now spamming the kernel-log with the following:
-
-[ 1099.190658] cpu cpu0: dev_pm_opp_set_rate: failed to find current OPP
-for freq 761142857 (-34)
-
-This only happens on certain devices like the Compex WPJ428
-and AVM FritzBox!4040. However, other devices like the Asus
-RT-AC58U and Meraki MR33 work just fine.
-
-The issue stem from the fact that all higher CPU-Clocks
-are achieved by switching the clock-parent to the P_DDRPLLAPSS
-(ddrpllapss). Which is set by Qualcomm's proprietary bootcode
-as part of the DDR calibration.
-
-For example, the FB4040 uses 256 MiB Nanya NT5CC128M16IP clocked
-at round 533 MHz (ddrpllsdcc = 190285714 Hz).
-
-whereas the 128 MiB Nanya NT5CC64M16GP-DI in the ASUS RT-AC58U is
-clocked at a slightly higher 537 MHz ( ddrpllsdcc = 192000000 Hz).
-
-This patch attempts to fix the issue by modifying
-clk_cpu_div_round_rate(), clk_cpu_div_set_rate(), clk_cpu_div_recalc_rate()
-to use a new qcom_find_freq_close() function, which returns the closest
-matching frequency, instead of the next higher. This way, the SoC in
-the FB4040 (with its max clock speed of 710.4 MHz) will no longer
-try to overclock to 761 MHz.
-
-Fixes: d83dcacea18 ("clk: qcom: ipq4019: Add the apss cpu pll divider clock node")
