[PATCH 3/4] rockchip: bob: Enable more configs

[Alper Nebi Yasak]

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 eMMC on this board is capable of running at a HS400 Enhanced Strobe
configuration, and the microSD slot at Ultra High Speed SDR104. Enable
the configs for these as the hardware supports these modes. There are
problems causing the devices to run at lower speeds, but these configs
are enabled in hope that these will be solved later. Enabling ADMA
currently makes the eMMC stop working, so it is kept disabled.

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.
