During system wakeup from suspend by connecting USB cable,
runtime PM framework transitions from enabled to disabled
state during i2c transaction. This causes asymmetric increment
and decrement of device's usage counter which blocks runtime
PM suspend callback.
To avoid this, remove rumtime PM status check on suspend path
to make it symmetric with the resume path. This takes care
of unaccounted increment/decrement of device's usage counter.

The commit 04a0136aeea5 ("clk: introduce CLK_ENABLE_HAND_OFF flag")
assumes that the first time clock client calls a clk_prepare &
clk_enable, the clocks from that point of time could be on their own.
But there could be use cases which could have impacts due to this
handling. Moving the handoff counts for prepare and enable at unused
tree level.

Some clocks are critical to system operation (e.g. cpu, memory, etc) and
should not be gated until a driver that knows best claims such a clock
and expressly gates that clock through the normal clk.h api.
The typical way to handle this is for the clk driver or some other early
code to call clk_prepare_enable on this important clock as soon as it is
registered and before the clk_disable_unused garbage collector kicks in.
This patch introduces a formal way to handle this scenario that is
provided by the clk framework. Clk driver authors can set the
CLK_ENABLE_HAND_OFF flag in their clk data, which will cause the clk to
be enabled in clk_register(). Then when the first clk consumer driver
comes along and calls clk_get() & clk_prepare_enable(), the reference
counts taken during clk registration are transfered (or handed off) to
the clk consumer.
At this point handling the clk is the same as any other clock which as
not set the new CLK_ENABLE_HAND_OFF flag. In fact no changes to any
clock consumer driver are needed for this to work.

Upon out of XO shutdown due to remote wakeup, as soon as XO gets
restored refclk is supplied to phy before even refgen current
is stabilized. USB3 controller asserts suspend_n signal asynchronously
for remote wake-up scenario solely based on utmi_linestate switching
from J state(suspend) to K state(resume). As a result phy attempts to
lock PLL since all prerequisites are met but, PLL lock attempt fails
and phy gets stuck. Since GCC_RX1_USB2_CLKREF_EN which was supposed to
control differential(CML) clock output to QUSB2 is a no-op, hence switch
to SE clock by PHY CSR controlled mux upon suspend. This prevents refclk
output to go directly to phy upon XO restore and prevents premature phy
pll locking. Phy PLL actually gets locked when phy driver switches back
from SE clk to diff clk.
