[U-Boot] [PATCH 3/9] board: ti: am57xx: Add support for detection of X15 revb1

[Lokesh Vutla]

BeagleBoard-X15 Rev B1 with SR1.1 platform have incompatible changes for HDMI
GPIO requiring new dtb support. This implies we have to properly identify
the platform now as well. Hence provide a different board name for the
Rev B1 variants.
