regmap: slimbus: fix buscontext pointer in regmap init calls

Commit 4e65bda8273c ("ASoC: wcd934x: fix error handling in wcd934xcodecparsedata()") revealed the problem in the slimbus regmap. That commit breaks audio playback, for instance, on sdm845 Thundercomm Dragonboard 845c board:

CPU: 5 UID: 0 PID: 776 Comm: aplay Not tainted 6.18.0-rc1-00028-g7ea30958b305 #11 PREEMPT Hardware name: Thundercomm Dragonboard 845c (DT) ...

The devmregmapinitslimbus() started to be used instead of regmapinitslimbus() after the commit mentioned above and turns out the incorrect buscontext pointer (3rd argument) was used in devmregmapinitslimbus(). It should be just "slimbus" (which is equal to &slimbus->dev). Correct it. The wcd934x codec seems to be the only or the first user of devmregmapinitslimbus() but we should fix it till the point where devmregmapinitslimbus() was introduced therefore two "Fixes" tags.

While at this, also correct the same argument in regmapinitslimbus().
