This adds the USB3 PIPE clock and GDSC structures, so
that the USB driver can vote for these resources to be
enabled/disabled when required. Both are needed for SS
and HS USB paths to operate properly. The GDSC will
allow the USB system to be brought out of reset, while
the PIPE clock is needed for data transactions between
the PHY and controller.

We are missing alwon ethernet clock for dm814x and this prevents us
from probing the CPSW with device tree only data. Looks like Ethernet
currently only works if it has been enabled in the bootloader.
Looks like relying on the bootloader clocks is not an issue with the
mainline kernel currently, but it will be an issue when configuring
CPSW Ethernet to probe with device tree data only as we will be managing
the clocks.

"This is some material that we picked up into our tree late, or that
had more complex dependencies on more than one topic branch that makes
sense to keep separately.
- TI support for secure accelerators and hwrng on OMAP4/5
- TI camera changes for dra7 and am437x and SGX improvement due to
better reset control support on am335x, am437x and dra7
- Davinci moves to proper clocksource on DM365, and regulator/audio

The secure clocks on omap5 are similar to what we already have for dra7
with dra7_l4sec_clkctrl_regs and documented in the omap5432 TRM in
"Table 3-1044. CORE_CM_CORE Registers Mapping Summary".
The secure clocks are part of the l4per clock manager. As the l4per
clock manager has now two clock domains as children, let's also update
the l4per clockdomain node name to follow the "clock" node naming with
a domain specific compatible property.
Compared to omap4, omap5 has more clocks working in hardare autogating
mode.

This is similar to what we have for omap5 except the gpu_cm address is
different, the mux clocks have one more source option, and there's no
divider clock.
Note that because of the current dts node name dependency for mapping to
clock domain, we must still use "gpu-clkctrl@" naming instead of generic
"clock@" naming for the node. And because of this, it's probably best to
apply the dts node addition together along with the other clock changes.
For accessing the GPU, we also need to configure the interconnect target
module for GPU similar to what we have for omap5, I'll send that change
separately.
