atmel_serial: Fix build on avr32 with CONFIG_PM enabled
AVR32 doesn't have at91_suspend_entering_slow_clock(). Just assume the
clock will keep running for now.
David has a better solution for this, but this works for now. Leaving
the USART clock running won't prevent the PM code from entering deep
power-down modes anyway.
