if we can get rid of usage of omap_hwmod_get_main_clk by catching them
with [1], then we can force the drivers to pick up based on device node
clocks= property.

It might be easier to fix 1 driver - timer, rather than introduce am33x,
omap4, omap5 dra7 specific "SoC clk driver".

with that this entire patch becomes redundant.
It is not that simple. Looking at the architectures this set supports, I
see clock alias nodes at least for following drivers:

- GPT timer
- USB
- DCAN
- EMAC
- VPFE
- UART
- SSI
- DSS
- security
- MMC
- MCBSP
- MCSPI

I am _not_ going to fix all of these during the initial phase. :P

But yes, eventually these should go away.
How many of these are needed to boot? what functionality do we expect 
with the series -> we can constraint saying that remaining drivers 
should fix themselves the right way, else dont have the feature - 
example cpufreq- fix it the right way, or wont see the feature enabled.

introducing a "way out" for all of these just invites more guys to screw 
around claiming "it was done before - see here"..

lets just fix the darned basic ones, refuse to provide "way out" and let 
the others fix themselves.
