pdc202xx_old: kill resetproc() method
The driver's resetproc() method resets both channels at once -- most probably
by driving RESET- on them. Not only such reset can severely disturb concurrent
operations on another channel, it also ensues 2-second delay, while there's no
apparent reason why SRST reset being performed prior to resetproc() call needs
to be followed up by another reset.
