x86/platform: Switch back to struct platform_driver::remove()

After

  0edb555a65d1 ("platform: Make platform_driver::remove() return void")

.remove() is (again) the right callback to implement for platform drivers.

Convert all platform drivers below arch/x86 to use .remove(), with the
eventual goal to drop struct platform_driver::remove_new(). As .remove() and
.remove_new() have the same prototypes, conversion is done by just changing
the structure member name in the driver initializer.
