[ Upstream commit 3046ec674d441562c6bb3e4284cd866743042ef3 ]

Commit 680a0873e193 ("arm: kernel: Add SMC structure parameter") added
a new "quirk" parameter to the SMC and HVC SMCCC backends, but only
updated the comment for the SMC version. This patch adds the new
paramater to the comment describing the HVC version too.
