The clock node is used by the serial driver and it's needed
before relocation.
This patch ensures that the msm-serial driver can actually
use the clock node.

I think the intent is to make dm-pre-reloc legacy.
New platforms should be using "u-boot,dm-spl" even if CONFIG_SPL_BUILD
is not enabled (I believe it should work)

another question is, how will you probe the clock driver before the uart?
I think even if you probed in misc_init_f it is already too late.
other than that - + Peter Robinson's comments- looks good.
