OMAP3/4 clock: split into per-chip family files

clock34xx_data.c now contains data for the OMAP34xx family, the
OMAP36xx family, and the OMAP3517 family, so rename it to
clock3xxx_data.c.  Rename clock34xx.c to clock3xxx.c, and move the
chip family-specific clock functions to clock34xx.c, clock36xx.c, or
clock3517.c, as appropriate.  So now "clock3xxx.*" refers to the OMAP3
superset.

The main goal here is to prepare to compile chip family-specific clock
functions only for kernel builds that target that chip family.  To get to
that point, we also need to add CONFIG_SOC_* options for those other
chip families; that will be done in future patches, planned for 2.6.35.

OMAP4 is also affected by this.  It duplicated the OMAP3 non-CORE DPLL
clkops structure.  The OMAP4 variant of this clkops structure has been
removed, and since there was nothing else currently in clock44xx.c, it
too has been removed -- it can always be added back later when there
is some content for it.  (The OMAP4 clock autogeneration scripts have been
updated accordingly.)
