mainboards/asrock/e350m1: Use driver for Nuvoton NCT5572D superio chip
On the ASRock E350M1 a Nuvoton NCT5572D is used as SuperIO-chip. The coreboot port to this board however used the driver of the Winbond W83627HF SuperIO, which is compatible enough to get most stuff working, but which clears bit 6 in register 0x2B. This switches the function of pin 38 of the NCT5572D from RSTOUT1# output to GP36. The PERST# pin of the ethernet chip and the unpopulated miniPCIe slot are connected to this pin, so they didn't get reset during a reboot.
Using the newly added driver for the Nuvoton NCT5572D fixes this problem.
There is also a trace from the pin 37 of the SuperIO, which can be configured as RSTOUT2#, to pin 82 of the USB3-chip with unknown function.
As with the wrong driver, PS/2 keyboard and mouse do work in SeaBIOS and GRUB but not in Linux.
