Subject: [PATCH v2 RESEND 0/2] Add Tegra ADMA channel page support

Multiple ADMA Channel page hardware support has been added from
TEGRA186 and onwards. Add channel page handling support in the tegra
adma driver

Changelog
=========

v1 -> v2:
---------
   * Removed '|' in the reg description
   * Included the allof:if:then: to describe the reg and reg-names
     properties to reflect exact restriction for all the Tegra platforms.
   * Replaced oneOf listing with items description   
   * Overall approach followed is to use either legacy single reg entry
     that encompasses the entire ADMA address space. This configuration
     ensures that the first channel page was always used. However, for
     Tegra186 and subsequent versions of platforms, opting for a more
     flexible approach to configure channel page address space
