dmaengine: tegra210-adma: prepare for supporting newer Tegra chips
This is a preparatory patch to add support for Tegra186 and Tegra194 chips.
Following changes are necessary to make driver code generic.
* chip_data structure is enhanced to have chip specific details and
following are the additions to the structure
* Offset addresses for ADMA global and channel registers
* Offset values for Tx and Rx channel selection
* Maximum supported Tx and Rx channels
* Tx and Rx channel request mask
* ADMA channel register space size
* Make use of above chip_data to generalise the driver code
Support for Tegra186 and Tegra194 will be added in subsequent patches of
the series.
