in SPI mode

Details:

Headers iom1284.h and iom1284p.h are lacking definitions for UCSR0C bit names
used only in SPI mode: UDORD0 (bit 2, aliases UCSZ01) and UCPHA0 (bit 1,
aliases UCSZ00).

This patch adds two appropriate #defines to both files mentioned above.

Follow-up Comment #1:

Thinking a little about it, I'm not that convinced yet about this.

All the modern ATmega-style devices (starting with the ATmega2560)
document these bits that way. So if at all, we'd have to patch
all their header files, to supply the UDORDn and UCPHAn bits.

However, these bits are nowhere else named that way. In particular,
none of the Atmel device description files mention these names, so
Atmel Studio doesn't know about them either.

But again: if we would really want to change something, then for
*all* devices that are affected, not just the ATmega1284*.
