[U-Boot] [PATCH] 85xx: properly document MPC85xx_PORDEVSR2_SEC_CFG

[Timur Tabi]

Commit f7d190b1 corrected the value of MPC85xx_PORDEVSR2_SEC_CFG, but forgot
to add a comment that the correct value disagrees with the 8544 reference
manual.  Without this comment, a developer looking at the code would get
confused.
