Update PPLL to 676MHz and PMU_PCLK to 48MHz, because:
1. 48MHz can make sure the pwm can get exact 50% duty ratio, but 99MHz
can not,
2. We think 48MHz is fast enough for pmu pclk and it is lower power cost
than 99MHz,
3. PPLL 676 MHz and PMU_PCLK 48MHz are the clock rate we are using
internally for kernel,it suppose not to change the bus clock like pmu_pclk

Some boards have a different set of USB controllers enabled in DT than
the set referenced by /alias entries. This patch fixes that. For
example, this avoids the following message while booting on Ventana,
which is caused by the fact that the USB0 controller had no alias, and
defaulted to wanting a sequence number of 0, which was later explicitly
requested by the alias for USB controller 2.

USB2:   Device 'usb@c5008000': seq 0 is in use by 'usb@c5000000'

This didn't affect USB operation in any way though.

Related, there's no need for the USB controller aliases to have an order
that's different from the HW order, so re-order any aliases to match the
HW ordering. This has the benefit that since USB controller 0 is the only
one that supports device-mode in HW, and U-Boot only supports enabling
device move on controller 0, there's now good synergy in the ordering! For
Tegra20, that's not relevant at present since USB device mode doesn't work
correctly on that SoC, but it will save some head-scratching later.

This patch doesn't fix the colibri_t20 board, even though it has the same
issue, since Marcel already sent a patch for that.

ARM: tegra: add APIs the clock uclass driver will need

A future patch will implement a clock uclass driver for Tegra. That driver
will call into Tegra's existing clock code to simplify the transition;
this avoids tieing the clock uclass patches into significant refactoring
of the existing custom clock API implementation.

Some of the Tegra clock APIs that manipulate peripheral clocks require
both the peripheral clock ID and parent clock ID to be passed in together.
However, the clock uclass API does not require any such "parent"
parameter, so the clock driver must determine this information itself.
This patch implements new Tegra- specific clock API
clock_get_periph_parent() for this purpose.

The new API is implemented in the core Tegra clock code rather than SoC-
specific clock code. The implementation uses various SoC-/clock-specific
data. That data is only available in SoC-specific clock code.
Consequently, two new internal APIs are added that enable the core clock
code to retrieve this information from the SoC-specific clock code. Due to
the structure of the Tegra clock code, this leads to some unfortunate code
duplication. However, this situation predates this patch.

Ideally, future work will de-duplicate the Tegra clock code, and migrate
it into drivers/clk/tegra. However, such refactoring is kept separate from
this series.

Aspect 1 is reasonable, but aspect 2 is a system-level decision, not
something that an individual peripheral driver should in general know
about or influence. Such system-level knowledge ties the driver to a

This patch enhances the Tegra core code to perform system-level clock
tree setup, in a similar fashion to the Linux kernel Tegra clock driver.
This will allow future patches to simplify peripheral drivers by removing
the clock parent setup logic.

This change is required prior to converting peripheral drivers to use the
standard clock APIs, since:

1) The clock uclass doesn't currently support a set_parent() operation.
Adding one is possible, but not necessary at the moment.

2) The clock APIs retrieve all clock IDs from device tree, and the DT
bindings for almost all peripherals only includes information about the
relevant peripheral clocks, and not any potential parent clocks.
