[patch 2.6.18+ ] scx200_hrt - fix precedence bug manifesting as 27x clock in 1 MHz mode

[Jim Cromie]

Fix paren-placement / precedence bug breaking initialization for 1 MHz 
clock mode.
Also fixes comment spelling error, and fence-post (off-by-one) error on 
symbol
used in request_region.

this patch fixes http://bugzilla.kernel.org/show_bug.cgi?id=7242
but I cannot close it, so I'll leave it to those so empowered.

should be ok for -stable, if the spelling correction doesnt break the rules.
The fence-post error is real, just not caught on x86, AFAICT.

Thanks alexander.krause@erazor-zone.de, dzpost@dedekind.net, for the 
reports and patch test,
and phelps@mantara.com for the independent patch and verification.
