lenovo/t530: Be safe by disabling blink gpio hw with a writeout 

This disables the blink hardware as it seems to be in the dump. This is
safer as it does not rely on 0 as the reset value when '0x00040000' is
the default according to the util/inteltool. As seen:

gpiobase+0x0018: 0x00040000 (GPO_BLINK) DIFF
