Commit 0918f18c7179 ("crypto: s5p - add AES support for Exynos5433")
introduced bug in dereferencing clk_names[1] on platforms different from
Exynos5433. On Exynos board XU3 call trace is:

"Unable to handle kernel paging request at virtual address 00004000"
(strcmp) from [<c0774014>] (of_property_match_string+0x58/0xd0)
...
(devm_clk_get) from [<c075c248>] (s5p_aes_probe+0xd4/0x4a0)
(s5p_aes_probe) from [<c059dbc4>] (platform_drv_probe+0x6c/0xa4)

Fix this by setting array clk_names size to 2.
