[0/4] platform/x86: ideapad-laptop: synchronize VPC commands

Hi,

Sometimes the Yoga mode control switch did not work properly on my 
laptop, and sometimes even caused a platform profile switch. It turned 
out that it was caused by a race situation, the lenovo-ymc wmi notify 
handler was running at the same time as the ideapad-laptop acpi notify 
handler, and the partial results of the VPC calls in the two were mixed 
up.

This series introduces a mutex and reorganizes the code a bit to 
eliminate this.

Best regards,
Gergo Koteles
