[PATCH v2 3/3] ARM: SIRF: make sirf irqchip driver optional since new SoCs will have GIC

From: Barry Song <Baohua.Song at csr.com>

New MARCO and POLO SoC use GIC, so make irq.c optional and enable it
only if we enable ARCH_PRIMA2 in Kconfig

Signed-off-by: Barry Song <Baohua.Song at csr.com>
 -v2: if dt node is not found, return but not panic since we might enable
 ARCH_PRIMA2 even we work on ARCH_MARCO
