A CLK_MUX_INDEX_BIT mux has one bit per parent, but the sun7i-a20-gmac-clk
has 2 bits selecting between 3 possible parents using values of 0, 1, 2,
which makes it a regular mux which should not have CLK_MUX_INDEX_BIT set in
its flag.
However we do not support parent 1 (an external clock), so use a table to
select parent 0 or 2, which are the 2 parents we support.
Note this has not been causing any issues sofar, because we start with a
parent setting of parent 0, and only ever re-parent to parent 2 (for which
we use an index of 1 as we skip parent 1) and with CLK_MUX_INDEX_BIT set
we write a value of 2 for index 1.
Tested on both a cubietruck (which uses rgmii mode) as well as a cs908
(an a31s board which uses mii mode).

This commit adds __iomem thoughout the sunxi clock driver, in places
where it was ommited. This cleans most of the sparse warnings we
are getting here.

Since we have a folder of our own, we can actually make use of it by
splitting the huge clock file into several sub drivers.
The gmac clock is pretty easy to deal with, since it's pretty much
isolated and doesn't have any dependency on the other clocks.
