The "Arm Ltd. Dual-Timer Module (SP804)" is a simple 32-bit count-down timer IP with interrupt functionality, and is used in some SoCs from various vendors. Add a simple DM compliant timer driver, to allow users of the SP804 to switch to DM_TIMER. This relies on the input clock to be accessible via the DM clock framework, which should be fine as we probably look at fixed-clock's here anyway. We re-program the control register in the probe() function, but keep the divider in place, in case this has been set to something on purpose before. The TRM for the timer IP can be found here: https://developer.arm.com/documentation/ddi0271/latest Signed-off-by: Andre Przywara <andre.przywara@arm.com>
