We configure network phy configuration for internal delay, LED config,
and clock config. If we leave the phy reset gpio defined in dt the
kernel may issue a reset to the phy and break these configs. While some
may be handled by a kernel phy driver, others may not (typically LED
config).

After mxc_ipuv3 DM_VIDEO conversion showing splash image
doesn't work. Fix this by adding new requirements:
- splashimage env variable.
- CONFIG_SPLASH_SCREEN
- CONFIG_CMD_BMP

Enable LVDS display detection and panel-specific configuration

Make I2C based LVDS detection and configuration model specific:
- not all boards support LVDS connectors; fail detection that do not
  support LVDS to avoid misdetecting an I2C device as a display
- GPIO configuration is panel specific; use panel name where needed

  To: u-boot, Stefano Babic, Fabio Estevam, NXP i . MX U-Boot Team; +Cc: Tim Harvey

Remove board_ehci_hcd_init function that is not used with DM_USB
and replace its functionality with device-tree configuraton that treats
USB HUB RST# as a gpio enable for the usbh1 vbus regulator.
