arm64: tegra: Add dma-channel-mask in GPCDMA node

Browse Source 
Add dma-channel-mask property in Tegra GPCDMA device tree node.

The property would help to specify the channels to be used in
kernel and reserve few for the firmware. This was previously
achieved by limiting the channel number to 31 in the driver.
Now since we can list all 32 channels, update the interrupts
property as well to list all 32 interrupts.
