To enable 48M clock USB PHY must be initialized since 48M
is output of USB PHY PLL.
So fix a problem where other devices requiring 48M clock will
not work unless USB OTG driver is enabled.
is_osc was removed from OTG drivers platform data and implemented
as separate function s3c6400_clk_xusbxti_is_osc which should be
called from machine_init. Currently there is no in-kernel users
of it.
This fix is only for S3C64xx family, but I am sure something
similar will be needed for S5P family. I have started the work
but I am unable to finnish it since I only have datasheet for
S5PC100. Maybe Samsung guys could help me with this..?
However current patches doesn't break S5P since it is not
using s3c-hsotg driver (yet?).
