Subject: [PATCH] acpi/drivers: add DMI exception for ASUS Vivobook E1504GA and E1504GAB to resource.c

Asus Vivobook E1504GA and E1504GAB notebooks are affected by bug #216158
(DSDT specifies the kbd IRQ as level active-low and using the override
changes this to rising edge, stopping the keyboard from working).
Users of these notebooks do not have a working keyboard unless they add
their DMI information to the struct irq1_level_low_skip_override array
in resource.c and compile a custom kernel. This patch will add support
for these computers to the linux kernel without requiring the end-user
to recompile the kernel.
