A previous optimisation incorrectly assumed the PAPR hcall does
not use r12, and clobbers it upon entry. In fact it is used as
an input. This can result in KVM guests crashing (observed with
PR KVM).
Instead of using r12 to save r13, tihs patch saves r13 in ctr.
This is more costly, but not as slow as using the SPRG.

Exynos5433 has two usb 3.0 controllers: usbhost and usbdrd. usbhost
is host-only controller whereas usbdrd supports both peripheral and
host mode. "drd" means dual-role device, so usbhost cannot be labeled
with the name containing "drd". However, the label usbdrd_dwc3_0 was
used for usbhost's dwc3 node. It seems it obviously fault because TM2
and TM2E doesn't use usbhost but dr_mode property is assigned to it.

As there is no way to actually query the hardware for the current clock
rate, now racalc_rate() just returns the last rate that was previously
set. But if the rate was not set yet, we return the bogus rate of 1000Hz.
The branch clocks have the same rate as their parent, so in this case we
just need to remove recalc_rate ops and then the core framework will handle
this automagically. The round_rate() is unused, so remove it as well.

This happens when the QP is in IB_QPS_RESET state and the stack
is trying to transition it to IB_QPS_ERR state in ipoib_ib_dev_stop().
According to the IB spec, Table 91 - "QP State Transition Properties"
it looks like the transition from reset to error is valid:
Transition: Any State to Error

Optional Attributes: None allowed
