Add m1n1-aurora and the silent uboot-asahi for Apple Silicon, aarch64 and edge only

Ported from the asahi-quattro lane. Both are pinned by hand like
linux-aurora and restricted to aarch64 and the edge channel from their
first merge, since merging publishes. pkgrel sits one above the fork
lanes' builds so the same filename never carries two sets of bytes.

+Subject: [PATCH] apple: keep the console silent on Macs
+
+Omarchy boots the Mac to a splash, not a terminal: with CONFIG_SILENT_CONSOLE
+the console is muted whenever the 'silent' variable is set, so the default
+environment sets it. Only U-Boot is silenced (CONFIG_SILENT_U_BOOT_ONLY);
+the kernel command line is untouched.

+The banner "U-Boot 2026.07 ..." is announced on the video console after
+relocation through console_puts_select(), which never looks at the silent
+flag; a silent console stays silent for the banner too.
