dm: timer: normalise SPL and TPL support 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).

aspeed: Add drivers common to all Aspeed SoCs Add support for Watchdog Timer, which is compatible with AST2400 and AST2500 watchdogs. There is no uclass for Watchdog yet, so the driver does not follow the driver model. It also uses fixed clock, so no clock driver is needed. Add support for timer for Aspeed ast2400/ast2500 devices. The driver actually controls several devices, but because all devices share the same Control Register, it is somewhat difficult to completely decouple them. Since only one timer is needed at the moment, this should be OK. The timer uses fixed clock, so does not rely on a clock driver. Add sysreset driver, which uses watchdog timer to do resets and particular watchdog device to use is hardcoded (0) Reviewed-by: Simon Glass <sjg@chromium.org>

Select this to enable timer for Aspeed ast2400/ast2500 devices.
This is a simple sys timer driver, it is compatible with lib/time.c,
but does not support any interrupts. Even though SoC has 8 hardware
counters, they are all treated as a single device by this driver.
This is mostly because they all share several registers which
makes it difficult to completely separate them.
