This adds the new board-specific clock init in mach-davinci/dm365.c
using the new common clock framework drivers.
The #ifdefs are needed to prevent compile errors until the entire
ARCH_DAVINCI is converted.
Also clean up the #includes since we are adding some here.

v10 changes:
- none
v9 changes:
- register PLL1 and PSC in dm365_init_time() instead of as platform device so
that we get the correct timer0 clock for davinci_timer_init()
- Fixed size of PLL memory block
v8 changes:
- none
v7 changes:
- add clock platform device declarations
- register platform devices instead of registering clocks directly
- add davinci prefix to commit description
v6 changes:
- add blank lines between function calls
