[PATCH 2/4] ARM: at91: sama5d3_xplained: drop invalid hostname

[Ahmad Fatoum <a.fatoum@pengutronix.de>]

From: Ahmad Fatoum <a.fatoum@barebox.org>

Host names can't contain underscores, so barebox complains at every
boot:

  WARNING: Hostname is not valid, please fix it

Without the override, the hostname is derived from the
"atmel,sama5d3-xplained" compatible instead, which is valid, so let's
drop it.

The net boot entry now looks for *-sama5d3-xplained instead of
*-sama5d3_xplained. This isn't worth a migration guide entry, as
barebox has been warning about the old name since v2024.05.0.
