rcar-gen3: linux-renesas: Upgrade Linux BSP to v3.6.2

This commit upgrades Linux BSP to v3.6.2 for following updates:

[Kernel]
- "WARNING: possible circular locking dependency detected" occurs with
repeating reboot. However, it was false positive, and it was confirmed
that there was no problem.
- Identify R-Car M3 Ver.1.2 or later.
- Remove lossy descompress area from MMNGR node and reduce reserved area
for R-Car E3 Ebisu board.

[Power Management]
- Improve power domains always on implementation.
- Fix interrupts are not raised issue on R-Car E3.
- Update CAS source.

[Display driver]
- Add overlay layer size check.
- Fix possible crtcs for plane when using VSPDL.

[IPMMU driver]
- Add workaround for disabling uTLBs.

[MSIOF driver]
Add MSIOF module clock changing processing for R-Car Series,
3rd Generation.

[PCIe driver]
- Fix memory leak in of_pci_get_host_bridge_resources.

[Thermal driver]
- Use DIV_ROUND_CLOSEST correctly as its description.

[USB3.0 Host driver]
- Cannot Suspend to RAM when enabling USB3.0.
- Confirm recognition of USB3.0 memory through HUB for setting
/etc/udev/rules.d/99-usb.rules.

[Video Capture driver]
- Allocate a scratch buffer at stream start. Then use scratch buffer
and always run in continuous mode.
- Fix PHTW register flow below 250 mbps.
- Fix clock control flow so that the warning message
“MSTP status timeout” is not displayed and when UDS (scaling)
is executed at VIN0, a black screen does not come out.
- Fix streaming procedure when resuming.

[Audio driver]
- Playback or capture doesn’t resume after Suspend to RAM.

[USB2.0 Function]
- Kernel error occurs with rmmod of g_printer.
- The dd command error occurs with g_mass_storage.

[USB2.0 Host driver]
- When connecting USB mouse, “Bad mode in Error handler” may occur with
Suspend to RAM.
