[PATCH v14 02/13] doc: Add doc for the Ingenic TCU hardware

Add documentation about the Timer/Counter Unit (TCU) present in the Ingenic JZ47xx SoCs. The Timer/Counter Unit (TCU) in Ingenic JZ47xx SoCs is a multi-function hardware block. It features up to to eight channels, that can be used as counters, timers, or PWM. - JZ4725B, JZ4750, JZ4755 only have s
