3d66f55161 kernel: improve handling of CONFIG_IO_URING
Kernel setting CONFIG_IO_URING supports high-performance I/O for file
access and servers, generally for more performant platforms, and adds
~45 KB to kernel sizes. The need for this on less "beefy" devices is
questionable, as is the size cost considering many platforms have kernel
size limits which require tricky repartitioning if outgrown. The size
cost is also large relative to the ~180 KB bump expected between major
OpenWRT kernel releases.

No OpenWrt packages have hard dependencies on this; samba4 and mariadb
can take advantage if available (+KERNEL_IO_URING:liburing) but
otherwise build and work fine.

Since CONFIG_IO_URING is already managed via the KERNEL_IO_URING setting
in Config-kernel.in (default Y), remove it from those target configs
which unconditionally enable it, and update the defaults to enable it
conditionally only on more powerful 64-bit x86 and arm devices. It may
still be manually enabled as needed for high-performance custom builds.

0c5ffe1ab2 x86: fix deprecated CONFIG_MICROCODE_OLD_INTERACE
We use late loading[1] so need to set this option despite upstream adding a
kernel taint when this option is set.  See discussion in PR#12149 for more details.

9fc2d58bf8 x86: fix damaged config 5.10 refresh
Restore CONFIG_I8K + CONFIG_INTEL_INT0002_VGPIO that got
removed when I refreshed the config. Each x86 target gets
its own CONFIG_CRYPTO_BLAKE2S + LIB settings as only the
x86_64 can use the accelerated x86 version.

Also remove two extra spaces that sneaked into geode's config.

72d2c54ccb kernel: 5.10: allocate last level PTEs in high memory
Enable support for allocating user space page table entries in high memory [1],
for the targets which support this feature. This saves precious low memory
(permanently mapped, the only type of memory directly accessible by the kernel).

fa3690f8f1 kernel: 5.10: consolidate mac80211 crypto options
Each of
- CRYPTO_AEAD2
- CRYPTO_AEAD
- CRYPTO_GF128MUL
- CRYPTO_GHASH
- CRYPTO_HASH2
- CRYPTO_HASH
- CRYPTO_MANAGER2
- CRYPTO_MANAGER
- CRYPTO_NULL2

either directly required for mac80211 crypto support, or directly
selected by such options. Support for the mac80211 crypto was enabled in
the generic config since c7182123b9 ("kernel: make cryptoapi support
needed by mac80211 built-in"). So move the above options from the target
configs to the generic config to make it clear why do we need them.

b61ab8f57e kernel: filter out both Clang and LLD versions
Both CLANG_VERSION and LLD_VERISON are autogenerated runtime
configuration options, so add them to the kernel configuration filter
and remove from generic and per-target configs to keep configs clean.

3326b5e75c treewide: switch the timer frequency to 100 Hz
Some targets select HZ=100, others HZ=250. There's no reason to select a higher
timer frequency (and 100 Hz are available in every architecture), so change all
targets to 100 Hz.
