It seems kfree(new_congested) does nothing since new_congested has already
been set null pointer before kfree, so remove it.

The current way to find if the PHY is internal is to compare DT phy-mode

But it will negate a possible future SoC where an external PHY use the

Compiling ebpf_jit.c with gcc 4.9 results in a (likely spurious)

When an AT91 programmable clock is declared in the device tree, register
it into the Power Management Controller driver. On entering suspend mode,
the driver saves and restores the Programmable Clock registers to support
the backup mode for these clocks.

Pipe clock comes out of the phy and is available as long as
the phy is turned on. Clock controller fails to gate this
clock after the phy is turned off and generates a warning.

PHY must be powered on before turning ON clocks and
attempting to initialize it. Driver is exposing
separate init and power_on routines for this.
Apparently USB dwc3 core driver performs power-on after
init. Also, poweron and init for QMP PHY need to be
executed together always, hence remove powero

Move from using array of clocks to clk_bulk_* APIs that
are available now.

PHY block or asynchronous reset requires signal
to be asserted before de-asserting. Driver is only
de-asserting signal which is already low, hence
reset operation is a no-op. Fix this by asserting
signal first. Also, resetting requires PHY clocks
to be turned ON only after reset is finished. Fix

Driver is currently performing PHY reset after starting
SERDES/PCS. As per hardware datasheet reset must be done
before starting PHY. Hence, update the sequence.

Use register layout to add additional registers present
on QUSB2 PHY V2 version for PHY initialization.
Other than new registers on V2, following two register's
offset and bit definitions are different: POWERDOWN control
and PLL_STATUS.
