linux: add patch to fix Zotac IR remotes

Zotac remotes use the customer code 0x80340000 and need the same toggle
bit handling as MCE remotes.

+Subject: [PATCH] media: rc: ir-rc6-decoder: enable toggle bit for Zotac
+ remotes
+
+The Zotac RC2604323/01G and RC2604329/02BG remotes use the 32-bit
+rc6 protocol and toggle bit 15 (0x8000) on repeated button presses,
+like MCE remotes.
+
+Add the customer code 0x80340000 to the 32-bit rc6 toggle
+handling code to get proper scancodes and toggle reports.
