arm(64): Replace write32() and friends with writel()
This patch is a raw application of the following spatch to the
directories src/arch/arm(64)?, src/mainboard/<arm(64)-board>,
src/soc/<arm(64)-soc> and src/drivers/gic:
@@
expression A, V;
@@
- write32(V, A)

@@
- write16(V, A)
+ writew(V, A)

- write8(V, A)
+ writeb(V, A)
This replaces all uses of write{32,16,8}() with write{l,w,b}()
which is currently equivalent and much more common. This is a
preparatory step that will allow us to easier flip them all at once to
the new write32(a,v) model.
