ARM: OMAP3+: clock33xx: Add AM33XX clock tree data 

AM33XX clock implementation is different than any existing OMAP
family of devices. Although DPLL module is similar to OMAP4
device, but the usage is very much different than OMAP4.
AM33XX has different peripheral set and each module gets
integrated to the clock framework differently than OMAP
family of devices.

This patch adds full Clock tree data for AM33XX family
of devices and also integrates it into existing OMAP framework.

[paul@pwsan.com: updated to apply; changed 'soc_is_am33xx' to
 'cpu_is_am33xx' to match usage in Tony's current am33xx branch]
