It turns out that sun4i (A10) and sun5i (A13 & co) do not have sample

Since these do not have sample clocks, they cannot (reliably) do
DDR rates, so only set MMC_CAP_1_8V_DDR when we do have sample clks.
Note this patch only changes the devm_clk_get error checking and sets
the clocks to NULL if they don't exists. All the clk_foo calls accept
a NULL clk and will return success when called with a NULL clk, so this
is all that is necessary.
The clocks aren't really optional. They're not needed for the A10 /
A13, and mandatory for the A20 and later.
Having a new compatible for the A20 that would require that clock and
not require it for the A10/A13 anymore seems more appropriate.
Ok, I've prepared a new version using a new compatible.

Hans
