[U-Boot] [U-Boot, v2, 2/6] dm: timer: normalise SPL and TPL support

[Philipp Tomsich]

> To fully support DM timer in SPL and TPL, we need a few things cleaned
> up and normalised:
> - inclusion of the uclass and drivers should be an all-or-nothing
>   decision for each stage and under control of $(SPL_TPL_)TIMER
>   instead of having the two-level configuration with TIMER and
>   $(SPL_TPL_)TIMER_SUPPORT
> - when $(SPL_TPL_)TIMER is enabled, the ARMv8 generic timer code can
>   not be compiled in
> 
> This normalises configuration to $(SPL_TPL_)TIMER and moves the config
> options to drivers/timer/Kconfig (and cleans up the collateral damage
> to some defconfigs that had SPL_TIMER_SUPPORT enabled).
