netx: Use get_irqnr_preamble to initialize base register
This patch optimizes the irq handling a bit. Now the base register is only computed once per irq exception instead of at least twice. Moreover the mov+add sequence is simplified to an ldr (which might save some cycles depending on memory timing). Signed-off-by: Uwe Kleine-König <u.kleine-koenig@pengutronix.de>
