[PATCH] platform/x86: ideapad-laptop: fix method name typo

[Barnabás Pőcze]

"smbc" should be "sbmc". `eval_smbc()` incorrectly called
the SMBC ACPI method instead of SBMC. This resulted in
partial loss of functionality. Rectify that by calling
the correct ACPI method (SBMC), and also rename
methods and constants.

BugLink: https://bugzilla.kernel.org/show_bug.cgi?id=212985
Fixes: 0b765671cb80 ("platform/x86: ideapad-laptop: group and separate (un)related constants into enums")
Fixes: ff36b0d953dc ("platform/x86: ideapad-laptop: rework and create new ACPI helpers")

Thank you I've added this to my review-hans branch.
I'll also add this to my fixes branch and include it in
a future pdx86 fixes pull-req for Linus for 5.13.

Thank you for your patch, I've applied this patch to my review-hans 
branch:
https://git.kernel.org/pub/scm/linux/kernel/git/pdx86/platform-drivers-x86.git/log/?h=review-hans

Note it will show up in my review-hans branch once I've pushed my
local branch there, which might take a while.

Once I've run some tests on this branch the patches there will be
added to the platform-drivers-x86/for-next branch and eventually
will be included in the pdx86 pull-request to Linus for the next
merge-window.

Regards,

Hans
