soc: mediatek: mtk-svs: Use pm_runtime_resume_and_get() in svs_init01()

[ Upstream commit 37fa2aff8fe490771f2229b0f2fcd15796b1bfca ]

svs_init01() calls pm_runtime_get_sync() and added fail path as
svs_init01_finish to put usage_counter. However, pm_runtime_get_sync()
will increment usage_counter even it failed. Fix it by replacing it with
pm_runtime_resume_and_get() to keep usage counter balanced.
