[PATCH V2 02/14] ppc/: fix some comment spelling errors


From: zhaolichang
Subject: [PATCH V2 02/14] ppc/: fix some comment spelling errors
Date: Fri, 9 Oct 2020 14:44:37 +0800

I found that there are many spelling errors in the comments of qemu/target/ppc.
I used spellcheck to check the spelling errors and found some errors in the 
folder.
