ASoC: tegra: propagate slave_id info to DMA engine

Browse Source 
ADMAIF default channel FIFO size is different depending on Tegra210 and
Tegra186 (and later). There is a guideline from HW that FIFO size of
ADMAIF channel should be same as the corrpsonding mapped DMA channel.
Commit 8c0d5ea47d21 ("dmaengine: tegra210-adma: override ADMA FIFO size")
updates FIFO size based on 'slave_id' info. Current patch passes the
'slave_id' information to DMA engine.

Following are the original commits from where the changes have been
manually cherry picked.
 - commit 34aa1f405069 ("ASoC: tegra-alt: T210 AHUB drivers")
 - commit 938afdfeea42 ("ASoC: tegra-alt: Alternative DAPM-based driver")

Also updated copyright info for Tegra PCM driver.
