tty: serial: vt8500: fix annotations for probe/remove

Fixes:

WARNING: drivers/tty/serial/built-in.o(.data+0x30): Section mismatch in reference from the variable vt8500_platform_driver to the function .init.text:vt8500_serial_probe()
The variable vt8500_platform_driver references
the function __init vt8500_serial_probe()

And mark the remove pointer while we are here.
