[PATCH] clk: ingenic-tcu: Fix missing TCU clock for X1000 SoC

From: Aidan MacDonald
Date: Wed Feb 09 2022 - 18:02:30 EST


The X1000 does have a TCU clock gate, so pass it to the driver.
Without this the TCU can be gated automatically, which prevents
timers from running and stops register writes from taking effect.
