davinci: ASoC: Add the platform devices for ASP
1) Registers the platform devices for ASP on dm355, dm644x and dm646x
so that the machine driver can probe to get ASP related platform
data.
2) Move towards definition of the asp clocks using physical name(for
dm355 and dm644x)
3) Add platform data to board specific files.
