kernel/ipq40xx: Restore kernel files for v6.1
This is an automatically generated commit which aids following Kernel patch history,
as git will see the move and copy as a rename thus defeating the purpose.

See: https://lists.openwrt.org/pipermail/openwrt-devel/2023-October/041673.html
for the original discussion.

4f7835cbf0 ipq40xx: enable CONFIG_LED_TRIGGER_PHY for AC42U
The AC42U already had PHY Triggers in the DTS.
We are probably going to use them at some point.

b8e52852bd ipq40xx: switch to performance governor by default
Doing a simple ping to my device shows this:

64 bytes from 10.0.253.101: icmp_seq=1 ttl=64 time=2.00 ms
64 bytes from 10.0.253.101: icmp_seq=2 ttl=64 time=2.02 ms
64 bytes from 10.0.253.101: icmp_seq=3 ttl=64 time=1.68 ms
64 bytes from 10.0.253.101: icmp_seq=4 ttl=64 time=1.91 ms
64 bytes from 10.0.253.101: icmp_seq=5 ttl=64 time=1.92 ms
64 bytes from 10.0.253.101: icmp_seq=6 ttl=64 time=2.04 ms

Some users even report higher values on older kernels:

64 bytes from 192.168.1.10: seq=0 ttl=64 time=0.612 ms
64 bytes from 192.168.1.10: seq=1 ttl=64 time=2.852 ms
64 bytes from 192.168.1.10: seq=2 ttl=64 time=2.719 ms
64 bytes from 192.168.1.10: seq=3 ttl=64 time=2.741 ms
64 bytes from 192.168.1.10: seq=4 ttl=64 time=2.808 ms

The problem is that the governor is set to Ondemand, which causes
the CPU to clock all the way down to 48MHz in some cases.

Switching to performance governor:

64 bytes from 10.0.253.101: icmp_seq=1 ttl=64 time=0.528 ms
64 bytes from 10.0.253.101: icmp_seq=2 ttl=64 time=0.561 ms
64 bytes from 10.0.253.101: icmp_seq=3 ttl=64 time=0.633 ms
64 bytes from 10.0.253.101: icmp_seq=4 ttl=64 time=0.526 ms

In theory, using the Performance governor should increase power draw,
but it looks like it really does not matter for this soc.

Using a calibrated precision DC power supply (cpu idle):

Ondemand
24.00V * 0.134A = 3.216 Watts
48.00V * 0.096A = 4.608 Watts

Performance
24.00V * 0.135A = 3.240 Watts
48.00V * 0.096A = 4.608 Watts

Let's simply switch to the Performance governor by default
to fix the general jittery behaviour on devices using this soc.

Tested on: MikroTik wAP ac

98bad1b4fc ipq40xx: 6.1: add missing secure QFPROM symbol
Kernel config for 6.1 on ipq40xx is missing the config for
CONFIG_NVMEM_QCOM_SEC_QFPROM which them makes the build stop with a prompt.

Symbol is there in 5.15 config but 6.1 config was based of a version that
does not yet have it set as it was introduced after the 6.1 PR.

So, disable CONFIG_NVMEM_QCOM_SEC_QFPROM to fix building on 6.1.
