Subject: [PATCH 09/26] soc: fsl: cpm1: qmc: Remove no more needed checks from qmc_check_chans()
The newly introduced qmc_chan_setup_tsa* functions check that the
channel entries are not already used.
These checks are also performed by qmc_check_chans() and are no more
needed.
Remove them from qmc_check_chans().
