Subject: [PATCH v7 09/19] dmaengine: tegra-apb: Remove unneeded initialization of tdc->config_init

There is no need to re-initialize the already initialized variables.
The tdc->config_init=false after driver's probe and after channel's
freeing, so there is no need to re-initialize it on the channel's
allocation.
