[char-misc-next 2/3] mei: me: store irq number in the hw struct.

From: Tomas Winkler

From: Alexander Usyskin <alexander.usyskin@xxxxxxxxx>

Store irq number in hw struct to by used by synchronize_irq().
This is to allow working with mei devices
embedded within another pci devices, via MFD framework,
where mei device is represented as a platform device.

Bump the copyright year to 2019 on hw-me.c and hw-me.h
