The marvell SATA driver can optionally make use of clocks specified in
the DT node. This has been available in the driver since Febuary 2012,
but the documentation is missing from the binding. Add it.
Signed-off-by: Andrew Lunn <andrew@xxxxxxx>

FYI: This will cause merge conflicts with the SATA PHY driver comming soon.
v1->v2:
s/pHandle/phandle/
Add specifier.
Not addressed yet is changing "0" to "port0", etc. Waiting for feedback
from Mark Rutland.
