[PATCH] Input: i8042: remove the modifications to i8042_platform_device

[Chen Jun]

i8042_platform_device can be changed in i8042_{probe|remove}.
This could leave a i8042 device on the platform bus and release resources
unexpectedly when i8042.ko is re-probed.

Fixes: 9222ba68c3f4 ("Input: i8042 - add deferred probe support")
