When CONFIG_INPUT=m, the input_*() family of functions is not
available to builtin drivers.
When CONFIG_RTC_CLASS is not set, rtc_tm_to_time64() is not defined.
Fix multiple build errors by making these Kconfig symbols required by
ADB_CUDA (RTC_CLASS) and ADB_PMU (RTC_CLASS and INPUT).

This is a big hammer type of patch. We could possibly do (a) some
conditional code blocks for RTC_CLASS and (b) only build via-pmu-event
if CONFIG_INPUT=y if needed.

Ah yes, Finn has already fixed the INPUT problems here.
Maybe that patch hasn't been merged anywhere yet?
The RTC_CLASS problem is still present AFAICT.

As far as I remember that's not enough, it leads to some warnings, see

As far as I remember that's not enough, it leads to some warnings, see
the threads around Finn's patch.

Shouldn't it be the other way round, ie 'select RTC_CLASS' ?

rtc_tm_to_time64() call sites also appear in several other files without
conditionals:
arch/powerpc/kernel/time.c
arch/powerpc/platforms/8xx/m8xx_setup.c
arch/powerpc/platforms/maple/time.c
arch/powerpc/platforms/powermac/time.c
Why not use mktime64() instead? That seems to be a common pattern for this
kind of thing (without needing conditional code).

I'll send a new version, though I expect it will attract comments too.
