[PATCH] media: rc: ir-rc6-decoder: enable toggle bit for Zotac remotes

[Matthias Reichl]

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.
