rcar-gen3: linux-renesas: Upgrade Linux BSP to v3.9.2

This commit upgrades Linux BSP to v3.9.2 for the following changes:

[Kernel]
- Add support for RCKSEL clock selection.
- Fix pin functions of R-Car E3 according to H/W UM Rev1.00 errata.
- Fix warning of the make W=1 C=2.
- Identify R-Car M3 Ver.1.3.
- Add the big.LITTLE CAS scheduler fix patches.
- Fix MOD_SEL bit numbering for R-Car E3.

[Power Management]
- Fixup power-domains of 3DGE for R-Car E3 Ver.1.0 and add device
tree file for R-Car E3 Ver.1.0.

[Audio Driver]
- Fixup clock start checker.
- Resolve the problem that the noise is generated during long playback
with R-Car E3 Ebisu-4D board by kernel rebasing.

[Display Driver]
- Add function of suspend and resume to adv7511_drv.c and add hot plug
event function at resume in rcar_du_drv.c.
- Add depends on DRM_RCAR_DU to config DRM_RCAR_LVDS.
- Revert "drm: rcar-du: Fix legacy DT to create LVDS encoder nodes".
- Add clock function for LVDS PLL.

[Ethernet Driver]
- Decrease TxFIFO depth of Q3 and Q2 to one.
- Fix not to call phy_resume() if PHY is not attached and add toggling
phy reset if PHY is not attached.
- Revert "ravb: RX checksum offload" for communicating of Q-Tag VLAN
frame correctly.
- Resolved the problem that the S2RAM resume failed on R-Car E3
Ebisu-4D by kernel rebasing.
- Avoid unsupported internal delay mode for R-Car E3 and limit to
100Mbps.

[I2C Driver]
- Check bus state before reinitializing.

[IPMMU Driver]
- Fix crash on early domain free.
- Revert "arm64: defconfig: Enable QCOM_IOMMU" for suspending with
LTSI kernel.
- Correct whitelist devices assignment.

[PCIe Driver]
- Avoid PCI device removing/rescanning through sysfs triggers
a deadlock.

[PWM Driver]
- Avoid deadlock warning when removing PWM device.

[SD/MMC Driver]
- Fix card initialization failure in high speed mode.
- Add adjust HS400 offset by manual calibration mode and adjust HS400
offset by manual calibration mode for R-Car M3 Ver.1.3.

[USB2.0 Function]
- Add reset_control.
- Backport upstream patches to support OTG mode for R-Car E3.
- Make DMAC system sleep callbacks explicit.
- Add Super-Speed (b-device) support.

[Video Capture driver]
- Review adv748x driver for R-Car E3 Ebisu board and add option for
changing SD output route to TXA.
- Revert "rcar-vin: rcar-csi2: Add blank margin when caluculating bit
rate" and fix pixel rate values.
- Add CPG reset and release when using digital pin.

[RWDT Driver]
- Don't keep timer value during suspend/resume.
- Don't set divider while watchdog is running.

This also updates ADSP driver patches to adapt to the new
Linux version.
