Linus Walleij 23f839816c clk: kirkwood: Fix a clocking boot regression 
commit aaedb9e00e5400220a8871180d23a83e67f29f63 upstream.

Since a few kernel releases the Pogoplug 4 has crashed like this
during boot:

Unable to handle kernel NULL pointer dereference at virtual address 00000002
(...)
[<c04116ec>] (strlen) from [<c00ead80>] (kstrdup+0x1c/0x4c)
[<c00ead80>] (kstrdup) from [<c04591d8>] (__clk_register+0x44/0x37c)
[<c04591d8>] (__clk_register) from [<c04595ec>] (clk_hw_register+0x20/0x44)
[<c04595ec>] (clk_hw_register) from [<c045bfa8>] (__clk_hw_register_mux+0x198/0x1e4)

[<c0acf3e0>] (kirkwood_clk_muxing_setup.constprop.0) from [<c0aceae0>] (of_clk_init+0x12c/0x214)
[<c0aceae0>] (of_clk_init) from [<c0ab576c>] (time_init+0x20/0x2c)
[<c0ab576c>] (time_init) from [<c0ab3d18>] (start_kernel+0x3dc/0x56c)
[<c0ab3d18>] (start_kernel) from [<00000000>] (0x0)
Code: e3130020 1afffffb e12fff1e c08a1078 (e5d03000)

This is because the "powersave" mux clock 0 was provided in an unterminated
array, which is required by the loop in the driver:

        /* Count, allocate, and register clock muxes */
        for (n = 0; desc[n].name;)
                n++;

Here n will go out of bounds and then call clk_register_mux() on random
memory contents after the mux clock.

Fix this by terminating the array with a blank entry.
