Liu Peibao cb122b6fb4 irqchip/loongson-liointc: Fix improper error handling in liointc_init() 
[ Upstream commit 4a60a3cdcf ]

For cores less than 4, eg, loongson2k1000 with 2 cores, the
of_property_match_string() may return with an error value,
which causes that liointc could not work. At least isr0 is
what should be checked like previous commit b2c4c3969f
("irqchip/loongson-liointc: irqchip add 2.0 version") did.

Fixes: 0858ed035a ("irqchip/loongson-liointc: Add ACPI init support")
