[ARM] Make kernel link address depend on PAGE_OFFSET
We are coding the kernel link address into the makefiles, which is
invisibly dependent on PAGE_OFFSET. If PAGE_OFFSET is changed, the
makefiles also need to be changed.
Make adjustments such that the makefiles encode just the offset from
PAGE_OFFSET for the kernel link address, and use PAGE_OFFSET in the
linker scripts directly.
