irqchip/irq-pic32-evic: Address warning related to wrong printf() formatter

[ Upstream commit 86be659 ]

This driver is currently only build on 32 bit MIPS systems. When building
it on x86_64, the following warning occurs:

    drivers/irqchip/irq-pic32-evic.c: In function ‘pic32_ext_irq_of_init’:
    ./include/linux/kern_levels.h:5:25: error: format ‘%d’ expects argument of type
     ‘int’, but argument 2 has type ‘long unsigned int’ [-Werror=format=]

Update the printf() formatter in preparation for allowing this driver to
be compiled on all architectures.
