[U-Boot] [PATCHv1 5/7] board: ge: bx50v3: use VPD instead of compile-time checks

[Sebastian Reichel]

From: Ian Ray <ian.ray at ge.com>

B{46}50v3s have an internal LCD that needs to be configured,
in comparison with B850v3 which has only external displays.

Use VPD instead of `CONFIG_TARGET_GE_B{4,6,8}50V3' compile-time
checks to correct initialize video based on the monitor type.
