- added timeout handling for i2c_writeout(); it seems that the
SAA7146 does not generate an I2C error irq when we are probing
for a non-existant device (so there's neither an ACK nor a NACK
at the end of the address phase)
- don't request the I2C error irq anymore, since it isn't currently
being handled; we just wait for the /BUSY irq or timeout; if there
were errors during transmission they will still be detected
from the status register after the /BUSY irq
- added some more debug to hw_interrupt()
TODO: I think SAA7146_I2C_TIMEOUT is too large; 10ms should do?
