sensor: lis2dh: cache CTRL1 on PM_DEVICE_ACTION_TURN_ON

Cache CTRL1 into reg_ctrl1_active_val inside lis2dh_init_chip()
in the PM_DEVICE_ACTION_TURN_ON path.  This prevents the first
runtime-PM RESUME from writing 0x00 to CTRL1 and disabling the sensor
when runtime-PM is enabled.

Fixes: zephyrproject-rtos#92196
