The APQ8064 HS USB controller nodes describe the transceiver clock as
"core", but the ChipIdea MSM glue expects "core" to be the controller
fabric clock and "fs" to be the transceiver clock.
This mismatch can leave the fabric clock disabled while the controller is
accessed. Some boards may tolerate that if the clock is already enabled
elsewhere, but it is not a correct description of the hardware.
Describe the RPM Daytona fabric clock as "core", the AHB clock as
"iface", and the transceiver clock as "fs" for all APQ8064 HS USB
controllers. Without this, USB does not probe reliably on Samsung Galaxy
S4 because the fabric clock remains disabled.
oh sorry, I forgot to mention that, depending on the feedback on
msm8960's patch [1], we might end up swapping the Daytona fabric and
HS1_H clocks. So, Daytona fabric would be the "iface" and HS1_H would be
the "core".
