Thanks for your help and my apologies for the breakage. I did not
expect this patch to enable build on non-ARM platforms but I can now
understand that the LPAE Kconfig bits may have been the last bit
stopping other architectures to build this driver.
I'm currently poking around with this driver on 32/64-bit ARM and
getting rid of those includes from asm/ is for sure on my TODO list.
