At present there are 3 irq router drivers. One is the common one and the other two are chipset specific for queensbay and quark. However these are really the same drivers as the core logic is the same. The two chipset specific drivers configure some registers that are outside the irq router block which should really be part of the chipset initialization. Now we remove these specific drivers and make all x86 boards use the common one. Signed-off-by: Bin Meng <bmeng.cn@gmail.com> Reviewed-by: Simon Glass <sjg@chromium.org>
