The renesas_usbhs_get_info() wrapper was useful for legacy board code.
Since commit 1fa59bda21 ("ARM: shmobile: Remove legacy board code
for Armadillo-800 EVA") in v4.3, it is no longer used outside the USBHS
driver, and provides no added value over dev_get_platdata(), while
obfuscating the real operation.
Drop it, and replace it by dev_get_platdata() in its sole user.

The dwc->maximum_speed is determined through the device capability and
designer's constraint through device tree binding. If none of them
applies, don't let the default coreConsultant setting in GUCTL1 to limit
the device operating speed.
Normally the default setting will not contradict the device capability
or device tree binding. This scenario was found through our internal
tests, not an actual bug in the wild.

The PPM might take time to process a reset. Allow 20ms for the reset to
be processed before reading the CCI.
This should not slow down existing implementations because they would
not set any bits in the CCI after a reset, and would take a 20ms delay
to read the CCI anyway. This change makes the delay explicit, and
reduces a CCI read. Based on the spec, the PPM has 10ms to set busy, so,
20ms seems like a reasonable delay before we read the CCI.
