[PATCH 5.12 063/127] platform/x86: ideapad-laptop: fix method name typo

From: Barnabás Pőcze <pobrn@protonmail.com>

commit b09aaa3f2c0edeeed670cd29961a0e35bddc78cf upstream.

"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.

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")
