rcar-gen3: linux-renesas: Upgrade Linux BSP to v3.7.0
This commit upgrades Linux BSP to v3.7.0 for following updates: [Kernel] - Change Linux version to v4.14.35 from v4.14. - Add support ZG clock divider for R8A77990 (R-Car E3). - Remove patch for Identifing R-Car M3 Ver.1.2 or later. [Power Management] - Fix "Using plain integer as NULL pointer" in rcar_ems_ctrl.c. - Add AVS support for gsx_opp_table. - Update SYSC power ON/OFF flow. [Display driver] - Fix procedure for extal and dotclkin selection for R-Car E3. - Add shutdown callback function in platform_driver". - Fix state flag in case of dual link mode for R-Car E3. [Ethernet driver] - Move reset-gpios property to EthernetAVB node for R-Car E3 Ebisu board. [I2C driver] - Fix handling of the RESTART phase and STOP phase. [MSIOF driver] - Add 2 clock delay by R-Car H3 Ver.3.0 only specification. [SD/MMC driver] - Fix eMMC HS400 mode setting. - Delete wait in tuning process. [USB2.0 Function] - Avoid wrong list handling in printer_write(). [USB2.0 Host driver] - Avoid the problem of Suspend to RAM in case of connecting USB mouse by removing following patches: <commit ID:cad25bf1> phy: rcar-gen3-usb2: Add the interrupt disabled in suspend <commit ID:318b535> phy: rcar-gen3-usb2: Support System Suspend To RAM [Video Capture driver] - Fix IFMD table information for R8A77990 (R-Car E3).

-Subject: [PATCH 1/6] soc: renesas: rcar-sysc: Update power control flow for
- SYSCEXTMASK register
-
-On H3 v3.0, it can observe the system hang up after changing
-power domains many times (~2000 times) continuously.
-This occurs because there is conflict when changing state
-of power domains.
-
-To overcome this issue, power domain on/off control flow
-need to be updated. It needs to set/clear value of SYSCEXTMASK register.
-
-This patch is updated for above purpose.
