platform/x86: lenovo-yogabook: Reprobe devices on remove()

Browse Source 
[ Upstream commit 711bcc0cb34e96a60e88d7b0260862781de3e530 ]

Ensure that both the keyboard touchscreen and the digitizer have their
driver bound after remove(). Without this modprobing lenovo-yogabook-wmi
after a rmmod fails because lenovo-yogabook-wmi defers probing until
both devices have their driver bound.
