With a later commit, the cpufreq core will call the ->set_boost()
callback only if the policy supports boost frequency. The
boost_supported flag is set by the cpufreq core if policy->freq_table is
set and one or more boost frequencies are present.
For other drivers, the flag must be set explicitly.
The policy->boost_enabled flag is set by the cpufreq core once the
policy is initialized, don't set it anymore.

It is possible to have a scenario where not all cpufreq policies support
boost frequencies. And letting sysfs (or other parts of the kernel)
enable boost feature for that policy isn't correct.
Add a new flag, boost_supported, which will be set to true by the
cpufreq core only if the freq table contains valid boost frequencies.
Some cpufreq drivers though don't have boost frequencies in the
freq-table, they can set this flag from their ->init() callbacks.
Once all the drivers are updated to set the flag correctly, we can check
it before enabling boost feature for a policy.

Currently it is left for the individual drivers to set the available and
boost frequencies related attributes in the cpufreq_driver->attr field.
Some drivers provide them, while others don't.
A quick search revealed that only the drivers that set the
policy->freq_table field, enable these attributes. Which makes sense as
well, since the show_available_freqs() helper works only if the
freq_table is present.
In order to simplify drivers, create the relevant sysfs files forcefully
from cpufreq core.
For now, skip adding them twice. This can be removed once all the
drivers are updated.

set_boost is a per-policy function call, hence a driver wide lock is
unnecessary. Also this mutex_acquire can collide with the mutex_acquire
from the mode-switch path in status_store(), which can lead to a
deadlock. So, remove it.

The CPU rate from clk_get_rate() may not be divisible by 1000
(e.g., 133333333). But the rate calculated from frequency(kHz) is
always divisible by 1000 (e.g., 133333000).
Comparing the rate causes a warning during CPU scaling:
"cpufreq: __target_index: Failed to change cpu frequency: -5".
When we choose to compare kHz here, the issue does not occur.

Compile-testing without CONFIG_OF leads to a harmless build warning:
drivers/cpufreq/airoha-cpufreq.c:109:34: error: 'airoha_cpufreq_match_list' defined but not used [-Werror=unused-const-variable=]
109 | static const struct of_device_id airoha_cpufreq_match_list[] __initconst = {
| ^~~~~~~~~~~~~~~~~~~~~~~~~
It would be possible to mark the variable as __maybe_unused to shut up
that warning, but a Kconfig dependency seems more appropriate as this still
allows build testing in allmodconfig and randconfig builds on all
architectures.
An earlier commit, b865a8404642 ("cpufreq: airoha: Depends on OF"),
tried to fix it incorrectly. ARCH_AIROHA already requires CONFIG_OF, so
this change does nothing, and the dependency is still missing for the
COMPILE_TEST case.
Fix it properly.
