This patch enables some configs that should be working on the Bob board, based on what is observed to work on the Kevin board.
The Bob board uses an Embedded DisplayPort panel compatible with the simple panel and Rockchip eDP drivers. Its backlight is controlled by the Chromium OS Embedded Controller Pulse Width Modulator. Enable these for the board.
Also set VIDEO_ROCKCHIP_MAX_{XRES,YRES} to 1280x800, the resolution of its panel. This had to be done for the Kevin board, but it's untested if this is actually necessary for Bob.
The Rockchip video driver needs to assert/deassert some resets, so also enable the reset controller. RESET_ROCKCHIP defaults to y for this board when DM_RESET=y, so it's enough to set that.
The Bob board has two USB 3.0 Type-C ports and one USB 2.0 Type-A port on its right side. Enable the configs relevant to USB devices so these can be used. This is despite a known issue with RK3399 boards where USB de-init causes a hang, as there is a known workaround.
Some other rk3399-based devices enable support for the SoC's random number generator in commit a475bef5340c ("configs: rk3399: enable rng on firefly/rock960/rockpro64"), as it can provide a KASLR seed when booting using UEFI. Enable it for Bob as well.
The default misc_init_r() for Rockchip boards sets cpuid and ethernet MAC address based on e-fuse block. A previous patch extends this on Gru boards to set registers related to SoC IO domains as is necessary on these boards. Enable this function and configs for it on Bob.
The microSD card slot on this board (and others based on Gru) is connected to a GPIO controlled regulator (ppvar-sd-card-io), which must be operable by U-Boot. Enable the relevant config option to allow this.
Bob boards also use the Winbond W25Q64DW SPI flash chip, enable support for Winbond SPI flash chips in the board config so U-Boot can boot with this chip.
