[PATCH 1/4] mfd: qnap-mcu: include linux/types.h in qnap-mcu.h shared header

[Heiko Stuebner <heiko@sntech.de>]

Relying on other components to include those basic types is unrelyable
and may cause compile errors like:

../include/linux/mfd/qnap-mcu.h:13:9: error: unknown type name ‘u32’
   13 |         u32 baud_rate;
      |         ^~~
../include/linux/mfd/qnap-mcu.h:17:9: error: unknown type name ‘bool’
   17 |         bool usb_led;
      |         ^~~~

So make sure, the types used in the header are available.
