[PATCH] shdmac: Remove misleading TODO comment in dmae_set_chcr

[Amin GATTOUT <amin.gattout@gmail.com>]

The comment suggested that the dmae_is_busy() check in dmae_set_chcr()
is superfluous and could be removed. However, this check serves as an
important safety net to prevent configuration of a DMA channel while
it is active. Keeping it helps ensure transfer integrity and avoids
unexpected hardware behavior in edge cases.
