linux-next: manual merge of the akpm tree with the arm-soc tree

[Stephen Rothwell]

Hi Andrew,

Today's linux-next merge of the akpm tree got a conflict in
drivers/ata/sata_mv.c between commit eee989902aab ("ARM: Orion: SATA: Add
per channel clk/clkdev support") from the arm-soc tree and commit
"ata/sata_mv: remove conditional compilation of clk code" from the akpm
tree.

I fixed it up (see below) and can carry the fix as necessary.

[I used the arm-soc version with all the conditionals on CONFIG_HAVE_CLK
removed.]
