staging: rtl8192e: Describe each kernel config option

An important thing people want to know is what each option that
they select in their kernel configuration file actually does, so
that they can select the right options for their system, and, once
booted, make sure their hardware works as expected.

Add more details describing each option in the kernel configuration
for the rtl8192e (rtllib) driver so that the end-user understands what
they mean, and, if necessary, enables/disables those features
if they are not required.
