93aa10cc5c cpu/avr8_common: Rework avr8_state variable 
The avr8_state variable uses bit operation to set/clear the state. This
rework avr8_state to use increment/decrement instead. It introduce the
use of General Purpose IO Register 1 (GPIOR1) when available.

This is a preparation for future scheduling and irq optimizations.

b7873015aa cpu/avr8_common: Split avr8_state 
The avr8_state store state information used to determine scheduling
and uart irq. This move all uart irq states to avr8_state_uart
variable. It introduce the use of General Purpose IO Register 0
(GPIOR0) when available and now all uarts from xmega can be used.

This is a preparation for future scheduling and irq optimizations.
