Move default cpufreq governor from ONDEMAND to PERFORMANCE. The temp
increase is just 2°C and Watt usage the change is minimal in the order
of additional millwatt. The SoC and krait in general looks to suffer for
some problem with cache scaling. To have better system stability, force
cpu freq and cache freq to the max value supported by the system. This
follows mvebu platform where cpufreq is broken and cause minimal
temp/watt increase.
User can still tweak the governor to ondemand using sysfs entry if
needed.

This allows loading modules with large memory requirements, recently needed
while testing on armvirt/32. Past forum discussions [1] and bug reports [2]
also raised this and the ipq806x target already set it in response [3].
Given this increases kernel image size by only ~1KB, is generally useful on
multi-platform kernels, and enabled by default on upstream arm32 Linux, add
it to the generic config.
The setting has similar utility on arm64, is a requirement for KASLR, and
already enabled on most OpenWrt aarch64 targets, so pull this into the
top-level generic config.

Since CONFIG_DYNAMIC_DEBUG is already managed via the KERNEL_DYNAMIC_DEBUG
setting in Config-kernel.in (default N), remove or disable it in target
configs which unconditionally enable it, along with the related setting
CONFIG_DYNAMIC_DEBUG_CORE. This saves several KB in the kernels for
ipq40xx, ipq806x, filogic, mt7622, qoriq, and sunxi.

Refresh target config with `make kernel_menuconfig`, then save the
result. This drops missing symbols or otherwise accounts for defaults.
It should not change any functionality.

It was tested that cache scaling currently cause instability problem.
This is probably caused by a latent misconfiguration that cause the L2
cache to be sourced from the wrong source and runs at an unstable freq
compared to the original QSDK fw.
To improve stability while the problem is bisected, disable the devfreq
drivers with minimal perf penality.

This commit add some enabled symbols to generic config.
LTO is only supported by clang compiler and therefore should
be disabled in the generic config instead of duplicating this
symbol in each target. CONFIG_LTO_NONE do this job.
The second group of symbols is enabled by the options available
in the generic config and is therefore added here:
* CONFIG_AF_UNIX_OOB is selected by CONFIG_NET && CONFIG_UNIX,
* CONFIG_BINARY_PRINTF is selected by CONFIG_BPF_SYSCALL,
* CONFIG_NET_SOCK_MSG is selected by CONFIG_BPF_SYSCALL && CONFIG_NET.
The other symbols are disabled and should be in the generic config.
This commit also removes these symbols from subtargets.
