In commit 23c8a500c24d02dd ("arm64: kernel: use ordinary return/argument register for el2_setup()"), we stopped using w20 as a global stash of the boot mode flag, and instead pass this around in w0 as a function parameter. Unfortunately, we missed a couple of comments, which still refer to the old convention of using w20/x20. This patch fixes up the comments to describe the code as it currently works.
