Shijie Qin ec7568ce2f LF-1220-2 mxc: vpu_windsor manage mailbox according to runtime PM 
Need to call mailbox's request/free channel according to runtime PM.
Ohterwise MUs power always 'on' during runtime suspend.

Remove requesting mu from probe, it will be requested through
pm_runtime_resume indirectly, so there is no need call it
directly.
