On x86, make allmodconfig && make W=1 C=1 reports:
WARNING: modpost: missing MODULE_DESCRIPTION() in drivers/irqchip/irq-ts4800.o
WARNING: modpost: missing MODULE_DESCRIPTION() in drivers/irqchip/irq-meson-gpio.o

Add the missing invocation of the MODULE_DESCRIPTION() macro to all
files which have a MODULE_LICENSE().  This includes a 3rd file,
irq-mvebu-pic.c, which did not produce a warning with the x86
allmodconfig, but which may cause this warning with other kernel
configurations.
