Cristian Ciocaltea 6dbef74aeb x86/cpu/amd: Enable Zenbleed fix for AMD Custom APU 0405 
Commit

  522b1d69219d ("x86/cpu/amd: Add a Zenbleed fix")

provided a fix for the Zen2 VZEROUPPER data corruption bug affecting
a range of CPU models, but the AMD Custom APU 0405 found on SteamDeck
was not listed, although it is clearly affected by the vulnerability.

Add this CPU variant to the Zenbleed erratum list, in order to
unconditionally enable the fallback fix until a proper microcode update
is available.
