coreboot/default bump: rev d862695f5f, 12 Oct 2023

Riku's mSATA patch for HP8300USDT was merged upstream, so the
patch has been dropped from lbmk because it is contained within
this new coreboot revision.

+Subject: [PATCH 20/22] ec/dell/mec5035: Add command to enable/disable radios
+
+These were determined by sniffing the LPC bus while toggling the
+hardware wireless switch on the Latitude E6400. To differentiate devices
+options in the vendor BIOS to change which radios the switch controlled
+were used.
