On MikroTik RB91x board series a reset key shares SoC gpio
line #15 with NAND ALE and NAND IO7. So we need a custom
gpio driver to manage this non-trivial connection schema.
Also rb91x-nand needs to have an ability to disable a polling
of the key while it works with NAND.
While we've been integrating rb91x-key into a firmware, we've
figured out that:
* In the gpio-latch driver we need to add a "cansleep" suffix to
several gpiolib calls,
* When gpio-latch and rb91x-nand fail to get a gpio and an error
is -EPROBE_DEFER, they shouldn't report about this, since this
actually is not an error and occurs when the gpio-latch probe
function is called before the rb91x-key probe.
We fix these related things here too.

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.

Commit f724a583dc updated the nand-rb4xx driver to the 5.10 testing
kernel, but forgot to add the new kernel config symbol it introduces to
the 5.10 config.

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.

Regulator support was enabled on all subtargets except for ath79-nand.
With Kernel 5.10, AT803x requires Regulator support, thus enabling on
the complete target, as ath79-nand requires AT803x.
While this is only required on Kernel 5.10, enable it also on 5.4. We
have no major size-constraint, so enabling it on 5.4 allows us to clean
up the occurences in the subtarget configuration.

This adds Kernel 5.10 support for the generic, nand and tiny subtargets.
The following patch is not contained, as it needs to be reworked:
