hwmon: (gpd-fan) initialize EC on driver load for Win 4

hwmon: (gpd-fan) initialize EC on driver load for Win 4

The original implement will re-init the EC when it reports a zero
value, and it's a workaround for the black box buggy firmware.

Now a contributer test and report that, the bug is that, the firmware
won't initialize the EC on boot, so the EC ramains in unusable status.
And it won't need to re-init it during runtime. The original implement
is not perfect, any write command will be ignored until we first read
it. Just re-init it unconditionally when the driver load could work.
