arm: tegra: suspend: Add board specific suspend/resume calls

Adding board specific suspend and resume call apis through platform
data.
Added call of these function at appropriate stage of suspend/resume.

Added mechanism to select the uart debug channel base address through
variable so that board file can directly change this.
