On the OMAP3430 architecture, some clocks are only available on
3430ES1 (e.g., the GFX subsystem, and the 16.8MHz input crystal rate
option) and some clocks are only available on 3430ES2 (e.g., DPLL5,
temp sensor, etc.) Now that OMAP3430ES revision detection is in the
tree, we can flag these so we do not try to initialize clocks that
don't exist on other ES revisions.
To do so, add new clock flags CLOCK_IN_OMAP3430ES1 and
CLOCK_IN_OMAP3430ES2, to be used for clocks that only exist on one
architecture or the other. CLOCK_IN_OMAP343X is still present and
used for clocks which exist on all 343X-level devices. The current
code assumes that production clocks will be identical to 3430ES2
clocks, but this is easy enough to change if necessary.
