The ahci-da850 SATA driver is now capable of retrieving clocks by
con_id. Add the connection id for the sysclk2-derived SATA clock.

I'm worry a bit - wouldn't this cause future problems with PM runtime
 (if it will be the case)?

If this is functional clock - shouldn't it be "fck" to
follow PM domain con_id list for davinci?  (arch/arm/mach-davinci/pm_domain.c)
I agree with Grygorii. Calling this clock "fck" will make it easy to
convert the DA850 AHCI driver to use pm_runtime at a future date (no
mach-davinci changes should be needed).

Sorry about not spotting this earlier.
Hi Sekhar,

I'll wait with sending v7 until we get an ack from Rob for the
ahci-da850 bindings, so that we don't fall to the bottom of the review
queue again.

Thanks,
Bartosz
