OMAP2 clock: drop DELAYED_APP clock flag

Browse Source 
All of the clocks that are marked with DELAYED_APP are changed as part
of the virt_prcm_set OPP virtual clock.  On 24xx, these clocks all
need to be changed as part of a group to keep the clock tree
functional - hence the need for the VALID_CONFIG bit, which is not
present on later OMAPs.  These clocks should not be rate-changed
independently.  So prevent these clocks from being changed
independently by dropping their .round_rate and .set_rate function
pointers.  It then turns out that the DELAYED_APP clock flag is no
longer useful, so drop it and the associated code and renumber the
clock flags.
