msm: clock-9625: Add NAND device for RPM clock handling

QPIC NAND has three clocks viz. gcc_qpic_system_clk, qcc_qpic_ahb_clk,
and gcc_qpic_clk. Need to set_rate and enable only qpic_clk and then
RPM will enable system_clk and ahb_clk as well.

Add NAND device to the list of RPM clocks to facilitate clock handling
for these QPIC clocks.

mtd: msm_qpic_nand: Add clock gating and bus bandwidth voting

QPIC NAND has three clocks viz. gcc_qpic_system_clk, qcc_qpic_ahb_clk,
and gcc_qpic_clk. Need to set_rate and enable only qpic_clk and then
RPM will enable system_clk and ahb_clk as well.

But the clocks are always on even when there are no requests to process.
So add support to gate/ungate the clocks accordingly. Also add support
to vote and unvote the bus bandwidth for better performance.

But if the clock is set and immediately suspend is triggered the clocks
would remain still enabled along with bus vote. So introduce both the PM
and Runtime PM suspend/resume to handle these cases as well.

ASoC: msm: Do not set volume to zero during session open

Setting stream volume to 0 will cause problem when user
starts playback from aplay. The previous volume which is
set gets overwritten with 0 when the playback starts. To
avoid this user space can control the volume setting at
the start of the playback.

msm: scm: Add logging of actual return code from scm call

When an error occurs during an scm call the error returned is
remapped so we lose the original error code. This means that
when an error occurs we have no idea what actually failed within
the secure environment.

Add a logging statement that will log the actual error code from
scm call allowing us to easier determine what caused the error
to occur.

msm: mdss: Introduce error checks for rotator sessions

When there are more virtual rotator sessions allocated than
DMA pipes available, rotator pipe allocations might fail and
corresponding error messages are printed which can lead to a
watchdog bark. This change silences those error messages and
also implements an extra check to avoid null pointer
dereference when a session is dequeued without a pipe.

usb: msm_otg: wake from apps power collapse during bus resume

In case D+ and D- MPM pins exists in the platform, turn on/off
the level shifter that drive these signals into the MPM as well
as the corresponding MPM pins.

This will allow the chip to wake up from apps power collapse by
the MPM when the USB cable is connected and USB bus resume occurred.

ARM: dts: msm: enable D+ HV interrupt for 9x25

On 9x25, the USB D+ and D- signals are routed from the HSUSB PHY to
dedicated MPM pins. This way the MPM can wake the chip  when these
signals change.

In this commit we enable only the D+ MPM pin, since we would like the MPM
to wake the chip on USB bus resume, which happens when the D+ is dropping.

ARM: dts: msm: shut off usb clocks on suspend for 9625

So far, when the usb bus was in suspend state the usb driver used
wake up interrupts from the usb bam to in order to start remote wake up
signal to the host due to a packet arrival in the bam pipe. In order
to this interrupt to work, we had to keep usb clocks enable during
suspend.

Today, after implementing handshake with the IPA resource manager, upon
start of remote wake up, the consumer will be first requested by the
resource manager to signal the usb to exit from low power mode, before
the first packet is pushed into the bam pipe, so before the wake up
interrupt will be received.

This allow us to shutdown the usb clocks during suspend and therefore to
support XO shutdown during suspend.
