Igor Grinberg 7a5d9a913f ARM: pxa: ulpi: fix ulpi timeout and slowpath warn
Both cm-x300 and pxa3xx-ulpi use the plain clk_{en,dis}able() API.
With the new clocking framework this results in warnings of type:
------------[ cut here ]------------
WARNING: CPU: 0 PID: 1 at drivers/clk/clk.c:714 clk_core_enable+0x90/0x9c

and alike...

And finally, it results in:
------------[ cut here ]------------
pxa310_ulpi_poll: ULPI access timed out!
OTG transceiver init failed
------------[ cut here ]------------

It might be that disabling the warning in kernel config would also do
the job, but IMO a better solution would be to switch to
clk_prepare_enable() and clk_disable_unprepare() APIs.
