drivers: serial: nrfx_uarte: Fix use of PM_DEVICE_ISR_SAFE
PM_DEVICE_ISR_SAFE shall not be used when non-asynchronous API is used
because RX is disabled in suspend action and that takes relatively
long time. In case of PM_DEVICE_ISR_SAFE it is done with interrupts
disabled. RX is not used at all if disable-rx property is set and in
that case PM_DEVICE_ISR_SAFE can be used.
Added macro which determines if ISR safe mode can be used.
